| 摘 要： | 目前,有限元方法已经广泛应用于机床分析及优化设计之中,有限元模型的准确性会对静动态分析产生巨大的影响,模态试验测试方法可以用于检验并修正模型。以某数控雕铣机为分析对象,将模态试验与有限元计算相结合,基于模态试验的动态参数测试结果,利用ANSYS Workbench有限元分析软件进行多目标优化设计,修正导轨结合面刚度参数,使矫正后的有限元模型更为准确地描述机床的动态特性。

| Abstract: | At present, the finite element method has been used widely in machine tool analysis and optimization of design, the accuracy of the finite element model will have serious effects upon static and dynamic analysis. Modal test method can be used to test and correct the model. This paper used a CNC carving the milling machine as analysis object, modal test combined with finite element metbod. Based on the dynamic parameters test results from modal test, used ANSYS Workbench to realize multi-objective optimization design, and corrected the joint surface stiffness parameters of the guide way, to make sure the corrected finite element model can accurately describe the dynamic characteristics of the machine tool. |
