Analytic superposition computation method of ring throttle slice deformation on non-uniform pressure

摘要

Based on the actual pressure condition of throttle slice of telescopic shock absorber, the non-uniform pressure was decompounded into a uniform pressure and a linearity non-uniform pressure. With the boundary and the continuity conditions, the general solution of throttle-slice deformation curved surface's differential equation on a linearity non-uniform pressure, was given, and by mathematical transformation, the deformation analytic formula was established. With the superposition principle, the deformation analytic formula of throttle slice on non-uniform pressure was established. With the practical example, the deformation of throttle slice on non-uniform pressure at any radius was computed, and was testified by ANSYS, the value computed is close to that simulated, and the relative deviation is only 0.0021%. The results shows that the method of deformation analysis computation of throttle slice on non-uniform pressure is reliable, which has important reference value for throttle slice thickness design and characteristic simulation modeling of shock absorber.
