Abstract :
For the design of throttle valves parameters based on multi-point speed characteristic, there is not any accurate and reliable CAD software for telescopic shock absorber. The speed characteristic of multi-points was analyzed, and the mathematic model of it was founded by nonlinear least square fitting. The optimization design method of curve fitting of valves parameters for multi-points speed characteristic is established. Based on this, the CAD soft ware of valves parameters of telescopic shock absorber was developed, and its characteristics were analyzed. A practical design example of valve parameters of telescope-shock absorber with the CAD soft ware was given, the performance test was conducted for the telescopic shock absorber designed by CAD. The experiment results show that the model of optimization design for the valves parameters based on multi-points speed characteristic is accurate, and the CAD soft ware is reliable.
