Abstract:

To get the expression of large deflection for telescopic shock absorber annular throttle-slice with its radius , based on the large deflection theory of circular plate, a intrinsic unified expression of thin plate deflection was put forward. Meanwhile, combined the large deflection's analytic expression of the annular plate's edge and the mature equation of small deflection, the mix analytical formula of large deflection for annular throttle-slices and its deformation correction factor related with radius were deduced. Moreover, the deformation of annular throttle-slice was simulated by finite element analysis software ABAQUS and the accuracy was verified. The analysis formula of superposition throttle-slices was established according to mix method. The equivalent thickness and stiffness of superposition throttle-slices were studied. The analysis formula and the conclusions can provide helpful reference for the future design and analysis of shock absorber throttle-slices.
