中文摘要：

通过三维软件Pro/E建立了机床滑座与床身的三维模型,采用Pro/MECHANICA软件建立了有限元计算模型.通过模态分析,计算了滑座与床身1至3阶的固有频率和振型,分析了各阶振动模态的特点,所得结果有利于机床支承系统的动态特性分析和整体设计.

英文摘要：

3D models of machine tool＇s slide and bed were built-up by the software Pro/E and the FEA models were established by Pro/MECHANICA.By the modal analysis,the 1st to 3rd ordered natural frequency and vibration mode of slide and bed were calculated.The analysis of vibration feature is useful to the dynamic analysis and overall design of machine tool supporting system.
