摘要：

Due to the complexity of structure and control on machining center, its reliability is usually difficult to ensure. In this paper, taking NBP1100 machining center spindle for example, the reliability virtual prototype model was built and the effects of thermal characteristics on reliability were analyzed. The spindle thermal reliability was analyzed by reliability simulation system in ANSYS. The distribution type and characteristic parameters of input variables were identified. The distributions of random sample variables were analyzed. The cumulative distribution function and failure probability of output variables were obtained. According to the sensitivity map, the main variables influencing spindle thermal characteristics were obtained. Methods and suggestions of improving spindle thermal reliability were also presented with the scatter diagrams.
