摘　　要：为解决某装备救生系统座舱盖作动筒液压腔接管嘴断裂导致的座舱盖下降问题,该文对产品的机上安装受力状态、产品工作原理、接管嘴无损检测、失效情况等展开分析,采取有限元仿真模拟和故障复现等手段确定了断裂原因为外力过载。结合故障原因以及断裂后引发的质量安全风险,制定了一系列措施,以杜绝因误操作等因素导致的接管嘴断裂的情况,确保产品性能稳定可靠。In order to solve the cabin cover descent problem caused by fracture of the nozzle in the hydraulic chamber of the operating cylinder in a certain equipment lifesaving system,research and analysis on the installation force state,the working principle of the product,non-destructive detection and judgment of the nozzle,and the failure analysis are conducted.Through the finite element simulation and the failure recurrence,it is determined that the fracture reason is the external force overload.Combined with the cause of failure and the severity of quality and safety caused by the fracture,the related measures to prevent the nozzle from breaking due to misoperation and other factors are worked out so as to ensure the stability and reliability of product performance.
