Description

Technical Field

[0001] The invention relates to the field of automated testing technology, in particular to a multi-freedom jumper cable simulation motion device. Background Art

[0002] The jumper cable is an indispensable transmission medium for realizing the transmission of optical and electrical signals between two adjacent carriages of a train. During the operation of the train, the jumper cable will undergo a composite motion composed of seven degrees of freedom, including vertical displacement, nodding, rolling, longitudinal displacement, left deflection, right deflection, and lateral displacement due to the relative movement of the two carriages. Specifically: longitudinal displacement: movement along the direction of rail laying; lateral displacement: movement along the cross-section direction of the track, and the difference in the lateral displacement direction is defined as the lateral difference, which specifically refers to the size of the edges of two adjacent carriages that are offset from each other; vertical displacement: movement in a direction perpendicular to the track; nodding (pitch): movement of the top or bottom of two adjacent carriages from a parallel state to an angled state; rolling: the rolling movement of the bodies of two adjacent carriages along the direction of rail laying; deflection: the rotational motion of the body around its respective center.

[0003] At present, the reliability of jumper cables is improved through standardized design, strict quality management, and improved manufacturing level. However, there is a lack of prior detection means, especially automated and digital operating condition testing (extreme position), fatigue strength testing (long-term operation characteristics), and tensile testing (monitoring the lowest point of the jumper cable). The source design and manufacturing problems can only be discovered through quality problems.

[0004] The prior art CN117709031A discloses a design method and simulation device for urban rail jumper cables, wherein the disclosed simulation device specifically includes a measuring base, a height limit adjustment plate, a projection measuring device, a wire drawer, a mobile clamp, a vertical movement module, a horizontal movement module, a fixed clamp, a clamp angle adjustment head and a jumper cable to be measured, wherein the vertical movement module and the horizontal movement module are used to drive the mobile clamp to move and adjust the relative position of the fixed clamp and the mobile clamp; the two clamp angle adjustment heads are used to adjust the inclination angles of the mobile clamp and the fixed clamp respectively; the projection measuring device is used to detect the lowest point of the jumper cable and the bending state of the connection with the mobile clamp and the fixed clamp to obtain the corresponding bending curvature radius; the wire drawer is used to reel or release the cable and adjust the cable length between the mobile clamp and the fixed clamp; the height limit adjustment plate is arranged below the fixed clamp and the mobile clamp.

[0005] Although the existing technology simulates the movement of the jumper cable between two adjacent train cars by driving the jumper cable to change horizontally, vertically and at an angle, the jumper cable actually moves with the train, especially when the train turns or moves on a section with a certain slope. The jumper cable not only moves horizontally and vertically and changes angles, but also has multiple motion scenarios such as vertical movement, side rolling, and flipping, and even the superposition of multiple motion scenarios. Therefore, although the existing technology can simulate the operation of the jumper cable to a certain extent, there is still a difference between the jumper cable and the actual operation of the train, resulting in inaccurate results of the simulation test. Summary of the invention

[0006] The purpose of the present invention is to provide a multi-degree-of-freedom jumper cable simulation motion device to solve the problem of the difference between the simulated jumper cable movement with the train operation and the actual jumper cable movement with the train pre-operation, improve the accuracy of the jumper cable simulation motion, and thus improve the accuracy of the simulation test results.

[0007] In order to achieve the above-mentioned purpose, the present invention adopts the following technical scheme: a multi-degree-of-freedom jumper cable simulation motion device, comprising: a frame; a left installation mechanism, used to realize the installation of jumper cables of different specifications on the left side and the setting of the initial angle on the left side; a right installation mechanism, symmetrically arranged with the left installation mechanism, used to realize the installation of the jumper cables on the right side and the setting of the initial angle on the right side; a longitudinal movement mechanism, used to simulate the relative movement of the left and right side mechanisms of the jumper cables along the direction of track travel; a transverse movement mechanism, used to simulate the relative movement of the two ends of the jumper cables along the cross-sectional direction of the track; a vertical movement mechanism, used to simulate the relative movement of the jumper cables in a vertical direction to the track; a nodding mechanism, used to simulate the relative movement of the jumper cables from a parallel state to an angle state at the top or bottom of two adjacent carriages; a side rolling mechanism, used to simulate the jumper cables between two adjacent carriages. The body of the car rolls along the direction of rail laying; the left deflection mechanism is used to simulate the rotational movement of the front end of the jumper cable around the center of the car body; the right deflection mechanism is symmetrical to the left deflection mechanism, and is used to simulate the rotational movement of the rear end of the jumper cable around the center of the car body; the height detection mechanism is used to monitor the lowest point of the jumper cable during multi-degree-of-freedom movement, and alarm when its lowest point exceeds the preset value; the human-computer interaction control module is used for human-computer interaction, input of working conditions and fatigue test technical conditions, multi-degree-of-freedom operation control and monitoring; wherein, the longitudinal movement mechanism is arranged on the frame, the nodding mechanism is arranged on the longitudinal movement mechanism and drives the nodding mechanism to move longitudinally, the side rolling mechanism is arranged on the upper side of the nodding mechanism, and the side rolling mechanism moves with the nodding mechanism, the left deflection mechanism is arranged on the upper side of the side rolling mechanism, the left mounting mechanism is arranged on the left deflection mechanism; the right mounting mechanism is arranged on the right deflection mechanism.

[0008] After adopting the above technical scheme, the present invention has the following advantages: when conducting a simulated motion test on the jumper cable produced according to the standard, the left end of the jumper cable is installed on the left mounting mechanism, and the initial angle position of the left end of the jumper cable before the test is adjusted by the left mounting mechanism, the right end of the jumper cable is installed on the right mounting mechanism, and the initial angle position of the right end of the jumper cable before the test is adjusted by the right mounting mechanism, the left mounting mechanism and the right mounting mechanism install the two ends of the jumper cable, the stability of the installation during the jumper cable test is improved, and the initial angle of the jumper cable before simulation can be adjusted to simulate the movement in different angle scenarios and improve the test accuracy; after the jumper cable is installed, the jumper cable is driven to move relative to the direction of track travel by the longitudinal movement mechanism, thereby simulating the movement of the jumper cable during the normal operation of the track car; the jumper cable is driven to move relative to the track cross section by the transverse movement mechanism The invention can simulate the shear motion of the jumper cable in the direction of the cross section of the track when the two adjacent carriages of the train turn by the vertical shift mechanism; simulate the vertical shear swing of the jumper cable when the train goes uphill or downhill by the vertical shift mechanism; simulate the nodding state of the jumper cable when the rear carriage goes downhill and the front carriage changes from downhill to uphill by the nodding mechanism; simulate the rolling motion of the jumper cable in the body of the two adjacent carriages along the laying direction of the rails by the side rolling mechanism; simulate the rotation motion of the front end of the jumper cable around the center of the car body by the left deflection mechanism; simulate the rotation motion of the rear end of the jumper cable around the center of the car body by the right deflection mechanism; make the jumper cable in the simulated motion detection, the simulated motion direction and motion form as close as possible to the actual motion of the jumper cable between the two adjacent carriages of the train, thereby improving the accuracy of the simulated motion test. In addition, the longitudinal movement mechanism is arranged on the frame, and the other mechanisms are arranged on the longitudinal movement mechanism in turn. During the test, the longitudinal movement mechanism can simulate the movement of the jumper cable as the train moves as much as possible, and the movement simulation in the other degrees of freedom directions can occur during the operation, thereby improving the accuracy of the jumper cable movement simulation.

[0009] Furthermore, the left mounting mechanism includes a first mounting base plate, a first fixed base, a rocker, a first sliding linear rail, a first sliding mounting plate, a first steering mechanism, a second steering mechanism, a left mounting truss and a left mounting module. The first sliding linear rail is arranged on the first mounting base plate, the first sliding mounting plate is arranged on the first sliding linear rail, the rocker is arranged on the first fixed base and is transmission-connected to the first sliding mounting plate, the first steering mechanism is arranged on the first sliding mounting plate, the left mounting truss is arranged on the first steering mechanism and the second steering mechanism, the left mounting module is arranged on the left mounting truss and is used for installing jumper cables of different specifications, the rocker is used to manually adjust and lock the first sliding mounting plate, and the first steering mechanism and the second steering mechanism are used to adjust the angle of the left mounting module.

[0010] Adopting the above-mentioned technical scheme, when the left installation mechanism is installed to adjust the angle of the left end of the jumper cable, the left end of the jumper cable is installed on the left installation module to stably install the left end of the jumper cable. After determining that the left end of the jumper cable is stable, manually turn the rocker to drive the first sliding installation plate to move along the first sliding track. During the movement of the first sliding installation plate, the angle of the left installation truss is assisted by the first steering mechanism and the second steering mechanism, and then the initial angle of the left end of the jumper cable is adjusted to improve the stability of the jumper cable installation. The rocker can also lock the position of the first sliding installation plate to avoid stability problems after the jumper cable is installed and affect the simulated motion test effect. The left end of the jumper cable is installed by the left installation mechanism to avoid the left end of the jumper cable from deflecting or detaching after installation and affecting the test effect of the simulated motion. Locking the position and angle of the jumper cable facilitates the simulation of motion in different angles. After the angle adjustment of the jumper cable is completed, the position is locked by the rocker to prevent movement, and the angle of the jumper cable changes during the simulation process and affects the simulation effect.

[0011] Furthermore, the first steering mechanism includes a first rotating shaft, a first connecting rod and a second rotating shaft, the first rotating shaft is arranged on the first sliding plate, the second rotating shaft is arranged on the left mounting truss, and the first connecting rod is arranged on the first rotating shaft and the second rotating shaft.

[0012] By adopting the above-mentioned technical solution, when the first steering mechanism assists in adjusting the initial angle of the left end of the jumper cable, the first rotating shaft moves closer to or away from the left mounting module as the first sliding mounting plate slides. As the first rotating shaft approaches or moves away, the angle between the axis of the first connecting rod and the horizontal plane changes, thereby adjusting the angle between the left mounting truss and the left mounting module, and then adjusting the initial angle of the left end of the jumper cable. The first rotating shaft and the second rotating shaft are connected by the first connecting rod, which facilitates the change of the angle between the axis direction of the first connecting rod and the horizontal plane, thereby adjusting the initial angle of the left end of the jumper cable, thereby avoiding the angle being too large or too small during the initial test of the jumper cable, thereby affecting the simulation test effect.

[0013] Furthermore, the longitudinal movement mechanism includes a second mounting base, a second sliding linear rail, a first rack, a first driving member, a second fixed base, a first gear and a second sliding mounting plate. The second sliding linear rail and the first rack are arranged on the second mounting base, the second sliding mounting plate is arranged on the second sliding linear rail, the second fixed base and the first gear are arranged on the second sliding mounting plate, the first gear is meshed with the first rack for transmission, the first driving member is arranged on the second fixed base and drives the first gear to rotate to drive the second sliding mounting plate to move relative to each other in the left and right directions to simulate the approach and separation of the jumper cable along the direction of travel of the track.

[0014] By adopting the above technical solution, when the jumper cable is driven to move by the longitudinal movement mechanism, the first driving member is moved, and the first driving member drives the first gear to rotate, and the meshing transmission of the first gear and the first rack drives the second sliding mounting plate to move along the second sliding linear rail, thereby driving the left end of the jumper cable to slide along the length direction of the first rack, thereby driving the motion simulation of the jumper cable when the train runs on the track, so that the subsequent motion simulation is more in line with the actual movement of the jumper cable when the train runs, thereby improving the accuracy of the motion simulation. The first gear and the first rack drive improve the stability of the transmission and avoid sudden pauses during the simulation process.

[0015] Furthermore, the transverse movement mechanism includes a second driving member, a third fixed base, a first ball screw, a third sliding rail and a third sliding mounting plate.

The third sliding rail is arranged on the third fixed base, and the third sliding mounting plate is arranged on the third sliding rail and transmission-connected to the first ball screw. The second driving member drives the third sliding mounting plate to move along the third sliding rail through the first ball screw to simulate the relative movement in the direction of the track cross-section at both ends of the jumper cable.

[0016] With the above technical solution, during the motion simulation, the second driving member is started, driving the first ball screw to rotate, and then driving the third sliding mounting plate to move on the third sliding linear rail, thereby driving the jumper cable to simulate the motion on the track cross section, and the first ball screw is driven by the second driving member to move forward and reversely, thereby improving the accuracy of the motion in the direction of the track cross section. The second driving member is fixed by the first fixed base to prevent the second driving member from being separated from the first ball screw and affecting the motion simulation in the direction of the track cross section.

[0017] Furthermore, the vertical movement mechanism includes a third driving member, a fourth fixed base, a second ball screw, a fourth sliding rail, a fourth sliding mounting plate, a first multi-link mechanism, a first connecting rod mounting base, a fifth sliding mounting plate, a fifth sliding rail, a fifth connecting mechanism and a support member. The first connecting rod mounting base and the fourth fixed base are arranged on the frame, the third driving member is arranged on the fourth fixed base, the fourth sliding mounting plate is arranged on the fourth sliding rail, the second ball screw is arranged on the fourth fixed base and is transmission-connected with the third driving member, one side of the first multi-link mechanism is arranged on the first connecting rod mounting base, and the other side is arranged on the fourth sliding mounting plate, the fifth sliding rail is arranged on the upper side of the first multi-link mechanism, and the fifth sliding mounting plate is arranged on the fifth sliding rail. The third driving member drives the second ball screw to move, thereby driving the fourth sliding mounting plate away from or close to the first connecting rod mounting base, and the fifth sliding mounting plate rises or falls as the fourth sliding mounting plate approaches or moves away from the first connecting rod mounting base, thereby driving the jumper cable to move vertically.

[0018] Using the above technical solution, during the simulation test, the third driving member drives the second ball screw to rotate, and then drives the fourth sliding mounting plate to slide along the fourth sliding linear track. When the fourth sliding mounting plate slides, it approaches or moves away from the first connecting rod mounting base, driving the lower end of the first multi-link mechanism to approach or move away from the first connecting rod mounting base. As the first multi-link mechanism approaches or moves away, the upper end of the first multi-link mechanism rises and falls, and then drives the end of the jumper cable to move in the vertical direction, thereby simulating the movement of the jumper cable in the vertical direction. When the fourth sliding mounting plate slides and drives the upper end of the first multi-link mechanism to rise and fall, it drives the fifth sliding mounting plate to move along the fifth sliding linear track, avoiding damage between the first multi-link mechanism and the fifth connecting mechanism due to angle changes, improving the strength of the equipment, and reducing the possibility of damage to the equipment during the simulation process.

[0019] Furthermore, the nodding mechanism includes a third mounting substrate, a fifth fixed base, a fourth driving member, a third ball screw, a sixth sliding linear rail, a sixth sliding mounting plate, a second multi-link mechanism and a second connecting rod mounting base. The fifth fixed base and the second connecting rod mounting base are both arranged on the third mounting substrate, the fourth driving member and the third ball screw are arranged on the fifth fixed base, and the fourth driving member is transmission-connected to the third ball screw, the third ball screw is transmission-connected to the sixth sliding mounting plate to drive the sixth sliding mounting plate to move along the sixth sliding linear rail, the second multi-link mechanism is arranged on the sixth sliding mounting plate and the second connecting rod mounting base, and the left and right sides of the top end of the second multi-link mechanism shake with the sliding of the sixth sliding mounting plate to drive the left end of the jumper cable.

[0020] By adopting the above-mentioned technical scheme, when the jumper cable is driven to simulate the relative movement from a parallel state to an angled state at the top or bottom of two adjacent carriages, the fourth driving member is started to drive the third ball screw to rotate, and then the sixth sliding mounting plate is driven to move along the sixth sliding linear rail. When the sixth sliding mounting plate moves, the lower side of the second multi-link mechanism moves with the sixth sliding mounting plate, driving the left and right sides of the upper end of the second multi-link mechanism to have a height difference, so that the jumper cable is turned from a parallel state to an angled state at the top or bottom of the two adjacent carriages. The jumper cable is similar to a nodding movement simulation in the direction of the carriage movement, which improves the accuracy of the operation of the jumper cable during simulated movement.

[0023] Furthermore, the left deflection mechanism includes a fifth mounting substrate, a sixth driving member, a fifth ball screw, a ninth sliding linear rail, an eighth sliding mounting plate, a second rack, a second gear and an annular slide rail mechanism. The sixth driving member, the ninth sliding linear rail and the annular slide rail mechanism are all arranged on the fifth mounting substrate. The sixth driving member is drivingly connected to the fifth ball screw. The eighth sliding mounting plate is arranged on the ninth sliding linear rail. The second gear is rotatably arranged on the eighth sliding mounting plate and connected to the left mounting mechanism. The left mounting mechanism is connected to the fifth mounting substrate through the annular slide rail mechanism. The second rack is arranged on the eighth sliding mounting plate and meshes with the second gear for transmission. The sixth driving member drives the eighth sliding mounting plate to slide through the fifth ball screw, and then drives the left mounting mechanism to deflect through the second gear.

[0024] By adopting the above-mentioned technical scheme, when simulating the left deflection motion, the sixth driving member is started, driving the fifth ball screw to rotate, and then driving the eighth sliding mounting plate to move along the ninth sliding linear rail, and the second rack moves with the eighth sliding mounting plate, and through the engagement of the second rack and the second gear, drives the second gear to rotate, and then drives the first mounting base plate located above the left flip mechanism to rotate, and then drives the left mounting module to deflect to the left, so as to simulate the left deflection of the jumper cable, and drives the jumper cable to deflect to the left through the second gear, the second gear and the annular slide rail mechanism, which facilitates the motion simulation of the left deflection of the jumper cable, thereby improving the accuracy and stability of the jumper cable motion simulation.

The one-way sliding mechanism is arranged on the support frame and is used to manually adjust the initial position of the detection. The sixth mounting substrate is arranged on the one-way sliding mechanism. The counter-radio grating is arranged on the sixth mounting substrate and is located at the lowest point for monitoring the jumper cables and issues an alarm after detecting the jumper cables.

[0026] By adopting the above-mentioned technical solution, a height detection mechanism is installed on the frame to control the height of the jumper cable during the movement simulation process. When the lowest point of the jumper cable is within the monitoring range, the incident light grating will issue an alarm to prompt the tester, thereby facilitating the control and monitoring of the jumper cable movement simulation test process.

When the rocking wheel 73 is rotated, the first lead screw 731 is driven to rotate, and then the first sliding mounting plate 741 is driven to slide along the first sliding linear rail 74. The first steering mechanism 75 is disposed between the upper side of the first sliding mounting plate 741 and the left mounting truss 77. The first steering mechanism 75 is horizontally arranged in two groups along the sliding direction perpendicular to the first sliding mounting plate 741. The first steering mechanism 75 includes a first rotating shaft 751, a first connecting rod 752 and a second rotating shaft 753. The first rotating shaft 751 is disposed on the upper side of the first sliding mounting plate 741, the second rotating shaft 753 is disposed on the left mounting truss 77, and the first connecting rod 752 is disposed between the first rotating shaft 751 and the second rotating shaft 753. The second steering mechanism 76 is disposed between the first mounting base plate 71 and the left mounting truss 77. Specifically, as shown in FIG. Figure 2 and Figure 3 As shown, the second steering mechanism 76 includes a first connecting plate 761, a third rotating shaft 762 and a second connecting rod 763. The first connecting plate 761 is disposed on the first mounting base plate 71. The third rotating shaft 762 is rotatably disposed on the first connecting plate 761. One end of the second connecting rod 763 is connected to the third rotating shaft 762 and the other end is connected to the left mounting truss 77.

The left installation connecting plate 781 is used to connect with the right side of the left installation truss 77.

The angle of the left mounting truss 77 is adjusted to adjust the angle of the left end of the jumper cable. When the rocker 73 does not rotate, the first sliding mounting plate 741 is locked, and the angle of the left mounting truss 77 is locked. After the jumper cable is installed on the left mounting plate 782 of the jumper cable, the initial angle of the left side is set by the rocker 73, the first sliding mounting plate 741, the first steering mechanism 75 and the second steering mechanism 76. The movement of the left end of the jumper cable can be simulated according to different initial angles.

When simulating the movement in the direction of track operation, the first driving member 24 is started to drive the first gear 26 to rotate. Through the meshing of the first gear 26 and the first rack 23, the first gear 26 moves relative to the first rack 23 in the direction of track operation, thereby driving the left end of the jumper cable to simulate movement in the direction of track operation. A first packaging cover 28 is provided between the lower side of the nodding mechanism 4 and the second sliding mounting plate 27 to hide the first driving member 24 and the first gear 26 and prevent the first driving member 24 and the first gear 26 from being exposed.

When the third driving member 81 is started, the fourth sliding mounting plate 85 is driven to move along the length direction of the fourth sliding rail 84 through the rotation of the second ball screw 83.

[0049] In this embodiment, if Figure 5 and Figure 6As shown, the first multi-link mechanism 86 includes a first fixed seat 861, a fifth link 862, a fourth rotation axis 863, a fifth rotation axis 864, a third link 865, a second fixed seat 866 and a third fixed seat 867. The first fixed seat 861 is provided with a plurality of links and distributed on the first link mounting base 87 and the fourth sliding mounting plate 85. The fifth link 862 and the third link 865 are cross-arranged and the cross position is hinged through the fifth rotation axis 864. The bottom end of the fifth link 862 is connected to the first link. The first fixed seat 861 on the rod mounting base 87 is hinged, and the top end is hinged to the second fixed seat 866, the bottom end of the third connecting rod 865 is hinged to the first fixed seat 861 on the fourth sliding mounting plate 85, and the top end is hinged to the third fixed seat 867, and the fifth connecting rod 862 and the third connecting rod 865 are horizontally distributed in the sliding direction perpendicular to the fourth sliding mounting plate 85. The bottom and top ends of the two fifth connecting rods 862 and the bottom and top ends of the two third connecting rods 865 are connected by the fourth rotating shaft 863.

[0050] When simulating the vertical movement of the jumper cable, the fourth sliding mounting plate 85 slides, and the fifth link 862 and the third link 865 rotate relative to the fifth rotation axis 864. Since the lower end of the fifth link 862 is fixed in the length direction of the fourth sliding linear rail 84, when the lower end of the third link 865 moves closer to or away from the first link mounting base 87 with the fourth sliding mounting plate 85, the top ends of the fifth link 862 and the third link 865 are driven to rise and fall, thereby driving the jumper cable to move vertically. The support member 802 is arranged between the first link mounting base 87 and the fourth sliding mounting plate 85. The upper end surface of the support member 802 is the lowest position during the vertical movement. When the simulated movement is in contact with the upper end surface of the support member 802, the support member 802 supports the transverse movement mechanism 3.

When the fifth connecting rod 862 and the third connecting rod 865 are raised or lowered, the fifth sliding mounting plate 88 is driven to move along the fifth sliding rail 89 by the top end of the fifth connecting rod 862, so as to avoid the transverse movement mechanism 3 affecting the vertical movement of the jumper cable after installation.

The third sliding mounting plate 35 is arranged on the third sliding rail 34 and is threadedly connected with the first ball screw 33. The right deflection mechanism 12 is arranged on the third sliding mounting plate 35. When simulating movement, the second driving member 31 is started to drive the first ball screw 33 to rotate, thereby driving the third sliding mounting plate 35 to slide, and driving the jumper cable to move along the length direction of the third sliding rail 34. The jumper cable is driven to move by the first ball screw 33, thereby improving the stability during the movement.

[0053] To simulate the relative movement of the jumper cables from the parallel state to the angle state at the top or bottom of two adjacent carriages, Figure 1 and Figure 8 As shown, the nodding mechanism 4 includes a third mounting substrate 41, a fifth fixed base 42, a fourth driving member 44, a third ball screw 43, a sixth sliding linear rail 45, a sixth sliding mounting plate 46, a second multi-link mechanism 47 and a second connecting rod mounting base 48.

The fourth fixed seat 471 is arranged on the upper side of the sixth sliding mounting plate 46. The bottom end of the fourth connecting rod 473 is rotatably connected to the fourth fixed seat 471 through the sixth rotating shaft 472. The fourth connecting rod 473 has two groups of The top ends of the two groups of fourth connecting rods 473 are respectively hinged to the lower side surfaces of the first support plate 477 and the second support plate 478, and the same group of fourth connecting rods 473 has two to improve stability; the seventh sliding linear rail 476 is arranged on the lower side surface of the first support plate 477, the seventh sliding mounting plate 475 is arranged on the seventh sliding linear rail 476, the top end of the fourth connecting rod 473 is hinged to the seventh sliding mounting plate 475 through the seventh rotating shaft 474, the third supporting plate 479 is arranged on the third mounting base plate 41 and can rotate relative to the third mounting base plate 41, and the third supporting plate 479 is arranged on the third mounting base plate 41.

In the initial position, the upper side surfaces of the first support plate 477, the second support plate 478 and the two third support plates 479 are in the same horizontal plane. When simulating movement, the fourth driving member 44 is started, and the third ball screw 43 is rotated, thereby driving the sixth sliding mounting plate 46 to slide along the length direction of the sixth sliding linear rail 45, thereby driving the fourth fixing seat 471 to move, causing the bottom end of the fourth connecting rod 473 to rotate with the sixth sliding mounting plate 46. The first support plate 477 is connected to the seventh sliding mounting plate 475 via the seventh rotating shaft 474 and the seventh sliding linear rail 476. The distance between the first support plate 477 and the second support plate 478 does not change with the shaking of the nodding mechanism 4. Therefore, during the sliding of the sixth sliding mounting plate 46, the plane where the upper side surfaces of the first support plate 477 and the second support plate 478 are located is deflected, thereby driving the relative movement of the jumper cable from a parallel state to an angled state at the top or bottom of the two adjacent carriages, thereby simulating the nodding movement of the jumper cable.

When simulating the side rolling motion, the fifth driving member 53 is started to drive the third multi-link mechanism 57 to slide along the length direction of the eighth sliding rail 56, thereby mobilizing the upper end of the third multi-link mechanism 57 to roll sideways, thereby driving the jumper cable to simulate the side rolling motion.
