Shock absorber performance testing device and method for vehicle engineering

A shock absorber performance testing device for vehicle engineering, comprising a box body and a box door, wherein a shock absorber body is provided in the box body, a U-shaped frame is fixedly connected to a bottom of the box body, a motor is fixedly connected to a bottom of the U-shaped frame, a rotating disk is fixedly connected to an output end of the motor, a moving block is connected to the rotating disk by a guide mechanism, two first connecting blocks symmetrically arranged are fixedly connected to a bottom of the moving block, two second connecting blocks symmetrically arranged are fixedly connected to a top of the rotating disk, insertion holes are formed on side walls of the first connecting block and the second connecting block, a plurality of groups of guide rods arranged in an array are fixedly connected to the bottom of the box body, two guide rods are arranged in each group of guide rods, retaining rings are fixedly sleeved on side walls of each group of guide rods, a first sliding block is slidably connected to the side walls of each group of guide rods, a counterweight block is fixedly connected to a top of the first sliding block, the counterweight block is pushed by a first pushing mechanism to move, a detection mechanism configured to detect movement of the moving block is arranged on the top of the rotating disk, and an oiling mechanism configured to automatically apply lubricating oil to the guide rod is arranged on the top of the first sliding block;

• the first pushing mechanism comprises a pushing block, the pushing block comprises a first inclined surface, the first sliding block slides on the first inclined surface, the first sliding block is connected to the top of the rotating disk by a lifting mechanism, a pointer is arranged on a side wall of the moving block, and a scale mark is arranged on a side wall of the pushing block;
• when the shock absorber body is subjected to performance test, two ends of the shock absorber body are respectively placed between the two first connection blocks and the two second connection blocks, and bolts are inserted into the insertion holes and into connection holes at the two ends of the shock absorber body for connection;
• the motor is started, and the motor rotates to drive the rotating disk to rotate;
• 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 and the counterweight block move downward under action of gravity and impact on the moving block, so that the shock absorber body is subjected to impact test;
• and a plurality of first sliding blocks and counterweight blocks are provided, so as to perform a plurality of continuous impact tests on the shock absorber body during the rotation of the rotating disk.
