Optimization design method of throttle slice thickness of telescopic shock absorber

Throttle slice thickness is the key factor that affects the characteristic of telescope-damper, but there is no any accurate and reliable design method. This paper analyzed the various damping factors which affect the design of throttle slice thickness, and the mathematics model that for throttle slice thickness by single velocity value is found with the analytic formula of throttle slice deformation and the relation formula of pressure with flux. Based on this, the target function of curve fitting optimization design for throttle slice thickness is established. A practical design example of throttle slice thickness of telescope-damper is given, the designed values is compared with that by single velocity and shown on the telescope-damper blueprint of factory. The performance test was conducted for the telescope-damper developed with the new design methods, and compared with the desired values, the tested values approach that desired. The experiment results show that the method of curve fitting optimization design for the throttle slice thickness is accurate, and the designed value is reliable and precision.
