Dynamic performance servo detection device for heavy-load oil-gas hybrid shock absorber

A heavy-load oil-gas hybrid damper dynamic performance servo detection device disclosed by the present invention comprises a bottom supporting platform and an oil storage tank, the top of the bottom supporting platform is sequentially provided with a supporting stand column and a telescopic rod from inside to outside, and the top of the surface of the supporting stand column is sleeved with a top cross beam. The top of the telescopic rod is fixedly connected with the bottom of the top cross beam, and the bottom of the bottom supporting platform is fixedly connected with an actuator. Through cooperative use of a guide sleeve mounting plate, a telescopic rod, a lower connecting rod, a top cross beam, a supporting stand column, an actuator, an oil distribution assembly, a tubular water cooler, a motor pump, a low-pressure energy accumulator, an oil source outlet valve group, a pump outlet valve and a 500kN servo linear actuator, the device has the advantage that the force and deformation measurement accuracy of
