Based on basic characteristic parameters of the combination, finite element modeling method of two kinds of combinations about rails and bolts were studied. They were used for the dynamic characteristics analysis of the machine tool. The dynamic test for the milling machine was done by vibration and noise testing equipment and the correctness of the finite element model was verified.%基于结合部基础特性参数,研究铣齿机床导轨和螺栓两种结合部的有限元建模方法,并将其用于机床整机的动态特性分析;采用振动噪声测试仪器对铣齿机进行动态测试,验证了有限元模型的正确性.
