[0016] S2: Start the motor, the rotation of the motor drives the rotation of the rotating disk, when the first inclined surface abuts against the first slider, the first slider is pushed to move upward along the side wall of the guide rod, and the counterweight block is driven to move upward synchronously, when the pushing block passes over the first slider, the first slider and the counterweight block can move downward under the action of gravity and impact on the moving block, so that the shock absorber body can be impact tested, and by setting a plurality of first sliders and counterweight blocks, the shock absorber body can be continuously impact tested multiple times during the rotation of the rotating disk;

Then, the motor is started, and the rotation of the motor drives the rotation of the rotating disk. When the first inclined surface abuts against the first sliding block, the first sliding block is pushed to move upward along the side wall of the guide rod, and the counterweight block is driven to move upward synchronously. When the pushing block passes over the first sliding block, the first sliding block is pushed upward along the side wall of the guide rod. When the first slider and the counterweight block are moved, the first slider and the counterweight block can move downward under the action of gravity and impact on the moving block, so that the shock absorber body can be impact tested. By arranging multiple first sliders and counterweight blocks, the shock absorber body can be impact tested multiple times continuously during the rotation of the rotating disk. At the same time, the moving speeds of the detection block and the moving block can be detected by the distance sensor, so the performance of the shock absorber body can also be tested. In addition, the frequency of the impact can be adjusted by adjusting the rotation speed of the motor and the rotating disk, so that the test is more convenient and quick and the test effect is better.

[0023] (3) The shock absorber performance testing device and method of this vehicle engineering, by setting an oiling mechanism, etc., when the first slider moves upward along the side wall of the guide rod, the second slider is driven to move upward synchronously through the first spring. When the surface of the guide rod is not lubricated enough, when the second slider and the first slider move upward, the second slider will be stuck.

In addition, the frequency of the impact can be adjusted by adjusting the rotation speed of the motor (12) and the rotating disk (13); S4: When testing, the adjusting nut (405) is rotated, and the rotation of the adjusting nut (405) drives the threaded rod (404) to rotate, thereby driving the threaded tube (403) and the first sleeve (401) to move up and down, and then driving the push block (201) to move up and down, and the scale mark (204) indicated by the penetrating pointer (203) is used to adjust the impact height of the first slider (207) and the counterweight (208), so as to facilitate the adjustment of the impact amplitude; S5: Furthermore, when the first slider (207) moves upward along the side wall of the guide rod (205), the second slider (501) is driven to move upward synchronously by the first spring (502). When the surface of the guide rod (205) is not lubricated enough, when the second slider (501) and the first slider (207) move upward, the second slider (501) may get stuck. At this time, the first spring (502) is compressed, and the distance between the first slider (207) and the second slider (501) becomes smaller, so that the end of the push rod (903) slides on the second inclined surface (902), thereby pushing The sliding plate (702) slides into the fixed cover (701), so that the circular hole (703) overlaps with the hose (602). At the same time, the second spring (804) is compressed.
