中文摘要：
根据HSK主轴系统的工作原理,在ANSYS软件中建立了HSK主轴系统的动力学模型。其中,各结合部都简化为均布弹簧单元,各部件简化为多段梁,并使用Timoshenko梁理论和有限元理论系统分析结合部对HSK主轴系统动态特性的影响。模态实验和有限元分析结果对比证实了Timoshenko梁理论分析HSK主轴系统动力学模型动态特性的可行性和有效性。提出结合部对主轴系统各阶模态影响的研究思路,并利用ANSYS有限元软件中的谐响应分析模块,分别研究了轴承-主轴、主轴-刀柄和刀柄-刀具各结合部对HSK主轴-热装刀柄-刀具系统刀尖点频响函数的影响,提出了相应的抗振措施。
英文摘要：
According to the working principles of HSK spindle system,a FEM （finite element method）dynamic model of HSK spindle system was built in ANSYS software,the joint parts were simplified as spring element and the parts were simplified as multi-parts beam.The dynamic perform-ance of HSK spindle system was analyzed with Timoshenko beam theory and FEM,and the modal ex-periments were made in HSK tooling system.The Timoshenko theory for analyzing dynamic per-formance of HSK spindle system was proved to be feasible,compared with modal results.At last, the joint parts affecting HSK spindle system tool point frequency response were studied,some anti-vi-bration solutions were proposed.
