摘　　要：简要阐述了振动模态及热模态有限元分析理论基础,分析解释了运用振动模态及热模态计算结果进行机床结构优化设计的原理依据。作为实例,分别利用ANSYS和COMSOL软件仿真计算了一台数控车削中心主轴箱的振动模态及热模态,根据计算结果提出了振动模态分析以调节固有频率为主、热模态分析以调节低阶热模态分布为主的结构优化设计方向,并分析了基于振动模态的结构设计与基于热模态的结构设计之间的相互影响。Schematically introduce the basic theory of vibration mode and thermal mode analysis and the feasibility of applying them to machine tool structure design is analyzed. As a demonstration example,the Vibration mode and thermal mode of a turning center headstock are simulated using ANSYS and COMSOL software respectively. According to the simulation results,the scheme of structure design that vibration mode analysis and thermal mode analysis are applied to optimizing machine tool structure from the angle of natural frequency and lower thermal modes distribution respectively is proposed. The interactions between structural designs based on vibration mode and thermal mode are analyzed.
