以机床主轴为优化设计对象，将优化设计思想与Matlab相结合，利用外惩罚函数法对机床主轴进行建模优化，求解出参数并用分支定界法确定主轴参数。然后运用ANSYS对其进行模态分析，分析了主轴的前6阶固有频率、振型和临界转速，验证了机床主轴结构优化设计的合理性，为机床主轴的结构优化设计提供参考和依据。
以機床主軸為優化設計對象，將優化設計思想與Matlab相結閤，利用外懲罰函數法對機床主軸進行建模優化，求解齣參數併用分支定界法確定主軸參數。然後運用ANSYS對其進行模態分析，分析瞭主軸的前6階固有頻率、振型和臨界轉速，驗證瞭機床主軸結構優化設計的閤理性，為機床主軸的結構優化設計提供參攷和依據。

Machine tool spindle is the object to be optimized and designed.Combined the opti-mum design idea and Matlab,the model optimization to machine tool spindle was put into prac-tice with penalty function.Then modal analysis was carried out by ANSYS.The first six lowest orders of the spindle,mode of vibration and critical speed of revolution were analyzed.And the rationality of structure optimum design of the spindle was verified.This research provides refer-ences to the structure optimum design of machine tool spindle.
