摘　　要：利用有限元分析软件ANSYS,建立KT-450高速数控雕铣机滑板系统和工作台系统的三维有限元模型,对滑板系统和工作台系统进行模态分析,得到了前8阶固有频率及模态振型,通过模态参数辨识给予验证。并提出改善机床动态特性的方法。The 3D finite element model of the sliding-plate and worktable system of KT450 hi-speed NC engraving and milling tool was established utilizing ANSYS. Based on the modal analysis of the sliding-plate and worktable system, the first 8 natural frequencies and vibration models were obtained, which were verified by the testing of modal parameter identification. Some methods to improve dynamic characteristics of the machine tool were put forward.
