摘　　要：根据高速冲床的结构和功能特点对其进行了子系统划分,针对其故障数据进行了统计分析,得到了故障分布信息。在此基础上,针对高速冲床提出了基于熵权法的故障危害性分析方法,对其各故障模式进行了危害性分析,得到了各故障模式和子系统的危害度。该方法完善了高速冲床可靠性分析技术。According to the structure and functional characteristics,high-speed punch machine is divided into several subsystems.The fault location distribution is obtained by statistical analysis.A failure criticality analysis method based on entropy weight method is proposed.And then,the criticality of each failure model and subsystem is obtained.Consequently,high criticality failure models and subsystems are determined.It improves the reliability analysis technology of high-speed punch machine.
