摘要:

为了同时满足特种车辆悬架减振器阀片应力强度设计及阻尼特性精确设计的需求,须采用变厚度节流阀片,然而目前尚无精确的变厚度节流阀片变形解析计算公式。根据变厚度节流阀片力学模型及曲面转角微分方程,建立变厚度阀片在均布压力作用下的变形解析计算式。利用ANSYS有限元软件对解析计算式正确性进行仿真验证,结果表明解析计算值与仿真值吻合且相对偏差在0.27%以内。通过实例,利用变形解析计算式对变厚度阀片进行设计并进行试验验证。试验结果表明,所设计的变厚度阀片同时满足了阀片应力强度与阻尼特性精确设计的要求,所建立的变厚度节流阀片变形解析计算方法是可 靠的。

Abstract:

To meet the requirements of throttle slice stress intensity and damping characteristics for special vehicle, the damper needs to adopt variable-thickness throttle slice. However, there is no accurate deformation analytic computation formula for it. Based on elastic mechanics theory, the general solution of the elastic surface differential equation for the throttle slice on linearity uniform pressure is given. Then, the deformation analytic formula is established. The deformation of the throttle slice at any radius is computed and testified by ANSYS. The results show the value computed is close to that simulated and the relative deviation is not more than 0.27%. With a practical example, by the deformation formula, the variable-thickness throttle slice is designed and validated by test. The test results show the valve designed meets the requirements of stress intensity and stiffness and the deformation analytic computation method is reliable.
