Stress Analytics Computation and Simulation for Throttle Slice of Shock Absorber

The deformation,internal forces and stress of throttle slice of shock absorber are analyzed using elasticity mechanics theory,and the slice stress coefficient and formula are found through the relation with the deformation.Followed is a practical example for radial,circumferential stress and complex stress computation and simulation of throttle slice with this method.The methods for stress computation and simulation are compared and the computation windages are analyzed.The compared results show that the stress coefficient analytics computation method is accurate enough,and throttle slice stress simulation is effective,not only to compute,but also to simulate the stress accurately at any radius position of single throttle slice.
