Abstract

In order to solve the problem of predicting damping characteristic of the shock absorber in the stage of design, a mathematical model for the shock absorber was built and simulated using the software Easy5. The establishment of the model was based on the analysis of internal configuration and working principle of double-tube hydraulic shock absorber, then using the parameters described the internal configuration of the shock absorber, and its core element ring throttle-slice was solved using small deflection theory. The calculated results agree well with the test data. The model can be used to study the effects of dynamic damping characteristic of the absorber on the vehicle performance.
