Optimum Design of Throttle-Valves Parameters for Shock Absorber Based on Velocity Characteristic

Throttle-valves parameters affect the characteristic of shock absorber, but at present, there is not any accurate and reliable analytic design method. In this paper, analyzed the various damping factors that affect the design of throttle-valves parameters, the design model of throttle-valves parameters by single velocity was founded, by the analytic formula of throttle-slice deformation and the relation of throttle-pressure with flux. Based on this, defined a target function, the optimization design method of throttle-valves parameters of curve fitting was established. A practical design example of throttle-valves parameters of one shock absorber followed, with this method. The designed results of throttle-valves parameters were compared with that shown on the blueprint of factory. The performance test was conducted for the telescopic shock absorber designed. The experiment results show that the model and method of optimization design for the throttle-valves parameters are reliable.
