基于ABAQUS的数控车床刀具刀架的有限元分析∗

摘要

在切削加工中，刀具的刚度、强度以及产生的共振等问题都会影响加工精度，是机械机构设计研究时不可忽视的问题，利用有限元分析软件ABAQUS对在粗车时对刀具的刚度和强度进行了静力学分析，对刀具刀架进行了模态分析，得到刀具刀架的前4阶固有频率和振型，并验证了刀具和刀架的设计均合理，所使用的研究方法为今后验证类似模型验证提供了参考依据。%In machining, tool rigidity, strength and resonance generated problems will affect the machining precision, which can not be ignored in mechanical design research, by using finite element analysis software ABAQUS,static analysis of stiff-ness and strength of tool in roughing is conducted, the modal analysis of tool turret is carried out, the first four natural frequen-cies and mode shapes of tool turret are got,and it is verified that the design tool and tool holder are reasonable, the research method in this paper provides a reference for the future similar model validation.
