根据减振器节流阀片力学模型,利用边界条件和变形连续性条件,给出了阀片在线性非均布压力作用下的变形曲面微分方程的通解.利用叠加原理,建立了减振器节流阀片在非均布压力下的变形解析计算式.根据阀片变形、内力和应力之间的关系,创建了在非均布压力下节流阀片径向、周向和复合应力解析计算式.通过实例,对节流阀片在不同非均布压力作用下的应力进行了解析计算,并利用ANSYS有限元软件进行数值仿真验证,解析计算结果与数值仿真结果吻合,相对偏差仅为1.41%.结果表明,所建立减振器节流阀片在非均布压力下的应力解析计算方法是正确可靠的,对减振器节流阀片设计和强度分析具有重要的应用价值.

According to the mechanics model of throttle slice of shock absorber,by the boundary and the deformation continuity condition,the general solution of the elastic surface differential equation of throttle slice on non-uniform pressure was given.With the superposition principle,the deformation analytic formula of throttle slice on non-uniform at any radius was established.With the relations of the deformation and inner force and stress of throttle slice,the analytic formulas of radial,circumferential and compound stress at any radius were given.With the practical example,the stress of throttle slice at any radius on non-uniform pressure was computed,and was testified by ANSYS,the value computed is close to that simulated,and the relative deviation is only 1.41%.The results show the method of stress analysis computation is reliable,which has important reference value for throttle slice thickness design and intensity analysis.
