Abstract

The present invention discloses a quality adjustable experiment device for measuring buffer shock resistance. The device comprises a workbench, a clamping module, a sliding module and weighting modules. The clamping module is configured to clamp two buffers to be measured, the clamping module is fixed at the top of the workbench, the sliding module is fixed at the top of the workbench, the weighting modules are arranged between the two buffers to be measured, and the bottoms of the weighting modules are arranged on the sliding module. The number of the weighting modules configured to bear impact is changed to regulate the quality of the weighting modules and carry corresponding speed, displacement and pressure sensors so as to obtain performance curves of buffers at different impact conditions, the structure is simple and reliable, and the production cost is low.

Description

technical field [0001] The invention belongs to the field of experimental devices, and in particular relates to a mass-adjustable experimental device for measuring the impact resistance of a buffer. Background technique [0002] Buffers are needed in many occasions with mechanical shocks (such as launching devices, automobile suspension systems, etc.), and the shock resistance of the buffers needs to be tested experimentally, which requires the use of buffer performance experimental devices. [0003] The existing shock absorber performance test devices are generally drop hammer or hydraulic type. They work under the condition of low frequency and cannot obtain the high-frequency dynamic characteristics of the shock absorber, so it is impossible to test the shock resistance of the shock absorber. For example, the impact force generated by the launching device has a short duration (about 0.3ms) and a large force amplitude (generally greater than 30kN). In order to explore whet...
