[0021] During the specific production, the upper fixing frame 1-1 and the lower fixing frame 1-4 are composed of multiple axial connecting rods and semicircular hoops arranged at intervals along the connecting rods. At the same time, the end covers at both ends are divided into two halves, which form a hollow cylindrical clamping cage with both ends blocked after closing; multiple lugs with through holes are made at the connection between the two, which are convenient for connection and fixation with multiple fastening bolts.

[0022] In a specific embodiment of the present invention, Figure 1 , 3 As shown, the movable module 2 includes a first support seat 2-1, a second support seat 2-2, a third support seat 2-3 and a fourth support seat 2-4 arranged from right to left, and the first support seat 2-1 is connected to the second support seat 2-2 on both sides of the bottom by two parallel sliding rods 2-5, and the bottoms of the second support seat 2-2, the third support seat 2-3 and the fourth support seat 2-4 are slidably matched with the base module 3. Among them, the first support seat 2-1, the second support seat 2-2, the third support seat 2-3 and the fourth support seat 2-4 all include a bottom plate 2-6 and a vertical plate 2-7, the second support seat 2-2 and the third support seat 2-3 share a bottom plate 2-6, and through holes are provided on both sides for sliding cooperation with the slide bar 2-5, the bottom plates 2-6 of the first support seat 2-1 and the fourth support seat 2-4 are fixedly connected to the slide bar 2-5; the vertical plates 2-7 and the upper surfaces of the bottom plate 2-6 are connected by triangular ribs 2-8, and the lower surface of the bottom plate 2-6 can slide with the slide rail 3-5 on the base module 3; the vertical plates 2-7 of the first support seat 2-1, the second support seat 2-2, the third support seat 2-3 and the fourth support seat 2-4 are parallel to each other, and the middle parts of the vertical plates 2-7 of the first support seat 2-1, the second support seat 2-2 and the third support seat 2-3 are provided with through holes; The first support seat 2-1 and the second support seat 2-2 are both in two groups, and the ribs 2-8 are arranged back to back.

Among them, the coupling adopts a plum blossom coupling to ensure reliable connection; the sliding rod is made of square steel pipe.

[0023] During specific production, the bottom plate 2-6 includes an upper plate, a lower plate and side plates on both sides thereof, the vertical plate 2-7 stands upright on the top of the upper plate, and the lower plate slides with the slide rail 3-5 on the base module 3. Since the bottom plates of the second support seat 2-2 and the third support seat 2-3 can move along the slide bar 2-5, it is convenient to adjust the distance between the first support seat 2-1 and the second support seat 2-2, which can meet the requirement that the clamp module moves backward instantly when the shell is fired.

[0024] Meanwhile, the middle through holes of the vertical plates of the first support seat 2-1 and the second support seat 2-2 are provided with bearing seats 10 for rotating with the shaft 1-5. The bearing seats are diamond-shaped, which can increase the stability of the fixture module and disperse the pressure during the launch process, and can also effectively fix the shaft.

[0025] In a specific embodiment of the present invention, Figure 1 , 4 As shown, the base module 3 includes a fifth support seat 3-1, a left slide seat 3-2, a right slide seat 3-3 and two parallel fixed rods 3-4, one end of the two fixed rods 3-4 is fixed to the bottom of the fifth support seat 3-1, and the other end of the two fixed rods 3-4 is fixedly connected to the two sides of the right slide seat 3-3; the left slide seat 3-2 is arranged between the fifth support seat 3-1 and the right slide seat 3-3, and the two sides of the left slide seat 3-2 are provided with through holes for sliding with the fixed rods 3-4, and the upper surfaces of the left slide seat 3-2 and the right slide seat 3-3 are provided with slide rails 3-5 for sliding with the movable module 2; both ends of the slide rails 3-5 are provided with limit plates 3-9 to limit their travel; the telescopic component 4 is connected to the fifth support seat 3-1. Among them, the slide rail 3-5 is a ball-bearing linear slide rail, and the sliders of the ball-bearing linear slide rails at both ends are respectively connected to the corresponding bottom plates on the movable module; the fixed rods are made of square steel pipes. The fifth support seat 3-1, the left slide rail seat 3-2, and the right slide rail seat 3-3 can be firmly connected together by using the fixing rod.

[0026] During specific production, the fifth support seat 3-1 includes a base plate 3-6 and a vertical plate 3-7. The vertical plate 3-7 stands upright in the middle of the base plate 3-6. Support plates 3-8 are respectively provided on the left and right sides of both ends of the vertical plate 3-7.

[0027] As a preferred solution, Figure 1 As shown, the telescopic component 4 is a hydraulic cylinder, the cylinder body of the hydraulic cylinder is fixed to the vertical plate of the fifth support seat, and the end of the piston rod of the hydraulic cylinder is rotatably connected to the vertical plate of the fourth support seat of the movable module. The end of the piston rod is rotatably connected to the connecting shaft 6 through a fisheye joint 5, and the connecting shaft 6 is connected to the vertical plate on the fourth support seat through a connector 7. The hydraulic cylinder moves instantaneously to simulate the recoil environmental force during the launch process. At the same time, the rotating component 8 is a motor. When the motor is started, the clamp module and the shells inside it rotate with the motor output shaft to simulate the centrifugal environmental force during the launch process.

[0028] In specific applications, the start, stop and speed of the hydraulic cylinder and motor can be controlled by the controller to achieve precise control.

[0029] The working principle of the present invention is as follows: When the dual environmental force simulation device is working, the hydraulic cylinder is started first, and the hydraulic cylinder moves instantly, which is transmitted to the active module and the fixture module through the fisheye joint, the connecting shaft and the connecting parts. At this time, the sliders on the ball-type linear slide rails at the left and right ends of the base module slide, driving the active module and the fixture module to move, thereby simulating the simulation of the recoil environmental force during the shell launch process. Then the motor in the active module is started, and its output shaft rotates. The rotation of the fixture module is controlled by the plum blossom coupling and the rotating shaft of the fixture module, thereby simulating the simulation of the centrifugal environmental force during the shell launch process. The simulation of the recoil environmental force is adjusted by controlling the size and flow rate of the oil pressure in the hydraulic cylinder, and the simulation of the centrifugal environmental force is adjusted by controlling the speed of the motor, thereby simulating the dual environmental forces, making the fuze test more comprehensive and accurate.

[0030] In summary, the present invention has the advantages of simple and reasonable structure, ingenious design, reusability, and effectively reduces the test cost. A hydraulic cylinder is used to simulate the recoil environmental force of the artillery shell firing process. By controlling the size and flow rate of the oil pressure in the hydraulic cylinder, a recoil high impact process similar to that during the artillery shell firing can be generated. At the same time, the hydraulic cylinder is more flexible than the traditional impact process, and can be quickly adjusted to adapt to the test of different firing environments, thereby improving the rapidity and safety of the test process. The rotation speed of the artillery shell is controlled by the rotation of the motor to simulate the centrifugal environmental force of the artillery shell firing process. The centrifugal environmental force of the firing process is simulated by adjusting the rotation speed of the motor, which is a relatively mature technology with high reliability and stability. The present invention can realize the loading of dual environmental forces, and more realistically simulate the recoil environmental force and centrifugal environmental force of the rotating ammunition firing process, which helps to more accurately evaluate the safety and reliability of the ammunition fuze assembly.

[0031] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention.
