[0050] When it is necessary to simulate the actual force conditions of the track magnet 101 and the vehicle-mounted magnet 102 under relative motion speeds during rotation, the servo motor I 22 can be controlled by the control panel 2 to drive the lead screw 24 to rotate or reverse, thereby causing the movable block 27 to move towards or away from each other. This, in turn, causes the movable block 27 to pull the fixed rod 26, causing the rotating seat II 8 to rotate or reverse, thereby causing the mounting seat I 9 and the vehicle-mounted magnet 102 to rotate or reverse. This results in the vehicle-mounted magnet 102 and the track magnet 101 no longer being aligned, thus presenting a rotating condition for both. Figure 18 and Figure 19 As shown; then the above operation can be repeated to measure the actual force between the track magnet 101 and the vehicle magnet 102 when in the rotating condition. After the measurement is completed, the servo motor I 22 is controlled by the operating panel 2 to drive the lead screw 24 to rotate and reset, thereby driving the movable block 27 to move and reset, and then the movable block 27 pulls the fixed rod 26 to drive the rotating seat II 8 to rotate and reset, thereby driving the mounting seat I 9 and the vehicle magnet 102 to rotate and reset, so that the vehicle magnet 102 is aligned with the track magnet 101;

[0051] When it is necessary to simulate the actual force conditions of the track magnet 101 and the vehicle magnet 102 under relative motion speeds in a figure-eight or inverted figure-eight configuration, the servo motor II 28 can be controlled by the control panel 2 to drive the worm gear I 29 to rotate or reverse, thereby causing the turbine I 30, mounting base I 9, and vehicle magnet 102 to swing towards or away from each other. Then, the servo motor III 31 can be controlled by the control panel 2 to drive the worm gear II 33 to rotate or reverse, thereby causing the turbine II 34, mounting base II 13, and track magnet 101 to swing towards or away from each other, thus creating a figure-eight or inverted figure-eight configuration between the track magnet 101 and the vehicle magnet 102. Figure 20 and Figure 21As shown; after that, the above operation can be repeated to measure the actual force between the track magnet 101 and the vehicle-mounted magnet 102 in the eight-shaped or inverted eight-shaped working condition, and after the measurement is completed, the servo motor II 28 is controlled by the operation platform 2 to drive the worm I 29 to rotate and reset, thereby driving the turbine I 30, the mounting seat I 9 and the vehicle-mounted magnet 102 to swing and reset, and then the servo motor III 31 is controlled by the operation platform 2 to drive the worm II 33 to rotate and reset, thereby driving the turbine II 34, the mounting seat II 13 and the track magnet 101 to swing and reset.

[0052] In this way, the actual force of the suspension module in different heights and relative motion speeds under each working condition can be measured by the above operation, and after all the measurements are completed, the track magnet 101 and the vehicle-mounted magnet 102 can be removed from the mounting seat I 9 and the mounting seat II 13, respectively.

[0053] Referring to Figure 10 and Figure 11 As shown, the three-dimensional force measuring device of the double-track permanent magnet suspension module further comprises a constant temperature mechanism, and the constant temperature mechanism comprises a heat preservation box 35, a box door 36, a temperature controller 37, a magnetic block I 38 and a magnetic block II 39.

The box door 36 is slidingly connected to the heat preservation box 35, and the box door 36 is made of glass material so that the tester can see the inside of the heat preservation box 35. The temperature controller 37 is connected to the top of the heat preservation box 35, and the temperature controller 37 is used for temperature control in the heat preservation box 35. Two magnetic blocks I 38 are connected to the left and right sides of the heat preservation box 35. Two magnetic blocks II 39 are connected to the left and right sides of the box door 36. The magnetic force of the magnetic block I 38 and the magnetic block II 39 can attract each other to fix the box door 36 on the heat preservation box 35.

[0054] In use, first pull the box door 36 to move downward to open, so that the upper magnetic block II 39 is separated from the upper magnetic block I 38, the lower magnetic block II 39 is separated from the lower magnetic block I 38, and the upper magnetic block II 39 is in contact with the lower magnetic block I 38, so that the lower magnetic block I 38 and the upper magnetic block II 39 are attracted by magnetic force to fix the box door 36, then the track magnet 101 and the vehicle-mounted magnet 102 are installed on the mounting seat I 9 and the mounting seat II 13 respectively, after the track magnet 101 and the vehicle-mounted magnet 102 are installed, pull the box door 36 to move upward to close, so that the upper magnetic block II 39 is separated from the lower magnetic block I 38, and the upper magnetic block II 39 is in contact with the upper magnetic block I 38, and the lower magnetic block II 39 is in contact with the lower magnetic block I 38, so that the magnetic block II 39 and the magnetic block I 38 are fixed to the box door 36 by magnetic force, then the temperature of the inside of the heat preservation box 35 is controlled by the temperature controller 37, so that the inside of the heat preservation box 35 is in a specified temperature range, thereby preventing temperature anomalies from affecting the magnetic field between the track magnet 101 and the vehicle-mounted magnet 102; then when the track magnet 101 and the vehicle-mounted magnet 102 need to be removed from the mounting seat I 9 and the mounting seat II 13 respectively, the above operation is repeated.

[0055] Referring to Figures 1-9 As shown in the drawings, the application also provides a measuring method of a double-track permanent magnetic suspension module three-dimensional force measuring device, comprising the following steps: first, the track magnet 101 and the vehicle-mounted magnet 102 are installed on the mounting seat I 9 and the mounting seat II 13 respectively, then the vehicle-mounted magnet 102 is driven to rise and fall by the hydraulic machine 3, so as to adjust the height difference between the vehicle-mounted magnet 102 and the track magnet 101, then the track magnet 101 is translated by the translation mechanism, so that the magnetic field between the vehicle-mounted magnet 102 and the track magnet 101 changes, and then the three-dimensional force sensor 4 measures the actual force between the track magnet 101 and the vehicle-mounted magnet 102 in the directly opposite working condition, after the measurement, the track magnet 101 is translated to reset by the translation mechanism, then the vehicle-mounted magnet 102 and the track magnet 101 are in the nodding, tilting, side deviation, rotating, eight-shaped and inverted eight-shaped working conditions in turn by the nodding mechanism, tilting mechanism, side deviation mechanism, rotating mechanism and eight-shaped structure according to the requirements, and the actual force of the suspension module in different heights and relative motion speeds in each working condition is measured in turn.
