摘　　要：为提升光电非接触式轴功率测量系统的可靠性,顺利完成船舶轴系工作状态实时监测任务,基于Isograph软件对该系统进行失效模式、效应与致命度分析。利用Isograph软件建立故障树,计算并分析该系统的各零部件对其可靠度的影响。针对该系统的薄弱环节(比如焊接的可靠性和码盘安装位置的准确性),利用有限元仿真分析软件ANSYS Workbench和三维建模软件Solidworks对系统的主要硬件(探头和码盘)进行模态分析,结果表明:在同一环境中,相比探头,码盘更易因强烈的振动而发生变形、断裂等机械故障。在实际应用该系统时,要保证组装、焊接的可靠性,以及码盘与轴线的垂直度;同时,根据机舱的实际工作环境,选用抗振性能较好的材料。The FMECA(Failure Mode and Effect Analysis)analysis on the photoelectric shaft power testing system is performed by means of software Isograph.The weak link of the system is defined based on the calculation of the FTA(Failure Tree Analysis).The modal analysis on probe and code disk is carried out by using software Solidworks and ANSYS Workbench.The analysis indicates that vibration may make the code disk severely deformed,which can guide the improvement of the existing system and effectively improve the reliability of the test system.
