摘　　要：建立了某坐标镗床主轴的实体模型,计算了在计算转速下的受力参数,依据实际载荷和边界条件,建立了有限元分析模型,分析了主轴在加工过程中的变形、应力和固有振动参数。分析结果表明,现有主轴力学性能满足要求。依据有限元分析结果,提出了减小机床加工误差的方法。The solid model of a kind of jig borer spindle was established. The force parameters were calculated. Using the actual force and boundary conditions, a model for finite element analysis of borer spindle was obtained. The distortion, stresses and vibration of the spindle were analyzed. The results show that the strength and rigidity of the spindle satisfy the design requirement. Several methods to reduce the machining errors were suggested.
