摘　　要：利用ANSYS软件对车削时的细长轴进行有预应力的模态分析,揭示车削转速、轴向力、跟刀架和中心架等的变化,对细长轴的刚度、振型的影响及其规律,从而得出提高细长轴车削质量的措施。Using ANSYS software the modal of a slender Axle turning on the Lathe was analyzed. The effects and laws of the slender Axle about vibration modal and dynamic rigidity were brought to the light, when-all sorts of conditions were changing, such as, principal axis turning speed of the lathe, axial direct force, follower rest, etc. Thereby, the quality of slender Axle to be machined on the lathe with relative measures was improved and raised.

关 键 词：ANSYS 预应力模态分析 固有频率 振型 动态刚度
