摘要

用力学理论对两直线导轨的载荷进行了分析。以VH1100型高速立式加工中心为研究对象，建立了永磁直线同步电机进给系统的简化力学模型。在简化力学模型的基础上，采用有限元法分析了运动部件在x轴不同行程时龙门式梁的变形。测量了梁的变形。通过有限元仿真和相关实验，得到了永磁同步电机的法向力。仿真结果与实测数据吻合较好，表明了模型的准确性。

Analysis of deformations of a machine tools' beam caused by linear motor's normal force

Loads of two linear guides have been analyzed by mechanics theory. A simplified mechanical model of Permanent Magnet Linear Synchronous Motor (PMLSM) feeding system is established with a VH1100 high-speed vertical machining centers as the object of study. On the basis of the simplified mechanical model, when moving parts are in different stroke of X-axis, deformation of a gantry type beam has been analyzed by finite element method. Deformation of the beam has been measured. The normal force of PMLSM has been achieved by finite element simulation and relevant experiments. The simulation results are in good agreement with measured data, indicating the accuracy of the model.
