摘　　要：建立了HT42160型数控龙门加工中心的左、右立柱和整机的三维及有限元模型,并分别进行了静、动态分析,借助ANSYS分析软件,得到了左、右立柱及整机在自由和约束状态下的前五阶固有频率和主振型,并在此基础上找出该龙门加工中心结构的薄弱环节,为龙门加工中心的结构优化设计提供理论依据和技术支持。The 3D and finite element mode of the whole machine body and the left/right upright post of TH42160 gantry machining center are established and with relevant static and dynamic analysis made, the nature frequency and the main vibration mode of the left/right upright post and the whole machine in both free and restricted states are gained using ANSYS software,based on which,the weak link in the structure of the gantiy machining center is found out,which can provide theoretical evidence and technical support for the structural optimal design of gantry machining centers.
