摘要： 在对主轴部件分析模型进行研究的基础上,采用弹簧阻尼单元模拟轴承支承的方法,建立了主轴部件动力学分析有限元模型.分别建立了采用两组和三组弹簧阻尼单元,且弹簧阻尼单元沿圆周方向以不同角度布置的机床主轴有限元模型,分析了不同支承情况及弹簧阻尼不同布置角度对主轴模态分析的影响.在对比分析的基础上,确定了合理的分析模型.以沈阳第一机床厂研制和开发的CHH6125高速数控机床主轴为对象,对主轴部件进行有限元模态分析和谐响应分析,并将其和机床试验的结果进行对比,验证了有限元分析模型的正确性.

Abstract: The finite element dynamic analysis model of the spindle assembly was developed by taking the advantage of the spring-damper elements to simulate the bearing supports. The FEA model were developed first by introducing 2 or 3 groups of circumferential spring-damper elements which were arranged at different angle around the spindle, then the effect of different supporting conditions and different arrange angles on the modal analysis of the spindle assembly were comparatively discussed to select the most rational FEA modal. The modal analysis and harmonic analysis were both made to confirm the dynamic characteristics of spindle assembly of CHH6125 high-speed NC machine tool developed and manufactured by Shenyang No.1 Plant of Machine Tools, and the results were compared with the testing ones. The correctness of the FEA model is available to the dynamic performance of the spindle assembly.
