摘要: 系统的失效模式优先级分析对系统的可靠性设计和可靠性分配具有重要的指导意义。电主轴作为现代高速精密机床的核心部件,要求具有较高的可靠性和更长的寿命。本文中应用决策实验室分析法,充分考虑了失效模式间的联系以及影响程度,对电主轴系统的主要失效模式进行了优先级分析,并结合与传统的风险优先数法的比较,为提高电主轴系统的可靠性和寿命提出了失效模式的优先次序意见。

Abstract: Priority analysis of system failure mode has important significance in reliability design and reliability allo-cation of system. Motorized spindle is one of the most important parts of modern high speed precision machine tool,and its high reliability and longer life spans have been required. The priority analysis of failure modes for the motor-ized spindle has been made by Decision Making Trial and Evaluation Laboratory (DEMATEL) technique,withfully considering the links between the failure modes and effects of the motorized spindle system. And the sugges-tion of failure mode priority to improve reliability of motorized spindle system has been proposed comparing with theconclusion of conventional Risk Priority Number (RPN) method.
