| 摘 要： | 首先采用有限元算法得到应力分布和预紧力计算结果,并根据计算结果,运用ANSYS的优化模块,对预紧簧片的厚度和预紧力进行迭代运算,直到得到满足设计要求的预紧力为止.优化结果显示,当簧片厚度为0.334mm时,所提供的预紧力与设计要求的38N最为接近.最后将仿真得到的最优结果与试验结果比较,得到了一致的结论.

| Abstract: | Firstly,according to the simulation result of the stress distributing and the pressure,the ANSYS optimization module was used to iterative calculate thickness and pressure of the pretightening reed until the pressure meets requirement.The optimization result proves that the provided pressure is nearest to required38N when the thickness of the reed is 0.334mm.Finally,the optimal simulation result is accordant with the experiment data,which provides design reference. |
