RESEARCH ON THE DEFLECTION OF THE ANNULAR THROTTLE SLICE OF SHOCK ABSORBER UNDER THE LOCAL VARIABLE LOAD

A research method for the deflection of throttle sliceunder the local distribution of variable load is presented. The analyticalequation is deduced using the plate theory according to the physical model ofthrottle slice, which is convenient for the theoretical analysis and engineeringapplication. The equation is validated by finiteelement calculation results. The relations between different loads,structure parameters, materials characteristics of throttle slice andthe deflections are studied. The analytical equation andconclusions offer some guidance to design throttle valve of shock absorber.
