摘　　要：多线切割机主轴是设备中最重要的部件之一,主轴的振动问题直接影响了一台设备的加工质量和生产效率。而主轴的临界转速是衡量主轴设计水平的一个重要指标,当主轴达到一定转速时,设备就会产生振动并伴有噪声。通过有限元模拟方法对主轴进行模态分析,求出其临界转速,为主轴转速设计提供了重要的理论基础。A spindle is one of the most important parts ina multi wire sawing machine. The vibrationof the spindle directly affects the quality of processing and productivity of the machine. However,thecritical revolution of the spindle is one of important specifications to verify the design level of thespindle. The machine will generate vibration as well as producing noise when the spindle revolutionreaches a certain value. The modal analysis of the spindle is carried out by the finite element simulationmethod in order to find the critical revolution of the spindle,which provides an important theory basisfor the design of the spindle revolution.
