摘要:
针对层状弹簧结构参数对其垂向刚度性能影响的问题，基于层状弹簧设计及生产应用经验，利用有限元仿真分析和试验相结合的方法，分析研究了橡胶层外径、橡胶层内径以及胶层厚度等层状弹簧关键结构参数对垂向刚度影响的规律，确定了层状弹簧垂向刚度理论计算公式，并进行了验证分析。结果表明：层状弹簧橡胶层外径对垂向刚度影响效果最为显著，起正向影响作用，影响灵敏度值约为5.5～7.7；橡胶层内径为负向影响，影响灵敏度值约为-1.7～-2.5；胶层厚度为负向影响，影响灵敏度值约为-2.1～-2.5；胶层数与垂向刚度呈反比影响关系。同时验证了理论计算公式的准确性。
Abstracts:
In view of the influence of structure parameters on vertical stiffness performance of layered spring, based on product design and production application experience, using a combination of finite element simulation analysis and product testing, the influencing pattern of key structure parameters of layered spring, including outer diameter of rubber layer, inner diameter of rubber layer, and thickness of rubber layer, on vertical stiffness is analyzed and studied. The theoretical calculation formula of layered spring vertical stiffness is concluded and verified. Results show that the outer diameter of layered spring rubber layer has the most significant effect on vertical stiffness, coming with a positive effect, with a sensitivity value of about 5.5~7.7; and the inner diameter of rubber layer comes with a negative effect, and sensitivity value of about -1.7~-2.5; thickness of the adhesive layer is negatively affected, with the sensitivity value of about -2.1~-2.5, and the number of adhesive layers is inversely proportional to the vertical stiffness. Accuracy of the theoretical calculation formula is verified.
