摘　　要：基于故障树分析方法对某型舰载燃气涡轮发电机组在安装调试过程中出现的异响故障进行诊断,根据故障特征找到14个可能引起故障的因素。逐一排查后得出故障诱因为:柱销联轴器中24个橡胶柱销的质量不一致造成的刚度分散。加强橡胶柱销的生产质量管理控制和在联轴器装配中增加橡胶柱销选配工序,确保了柱销的质量一致性与刚度均匀性。Based on the fault tree analysis method, the anomaly sound fault of a marine gas turbine generator during installation and debugging was diagnosed. According to the fault characteristics, 14 factors that may cause the fault were found. After trouble shooting one by one, the stiffness dispersion caused by the inconsistent mass of 24 rubber pin of couplings was found to be the incentive of anomaly sound fault. The solution was made to strengthen the production quality control of rubber pin and enhance the selection process of rubber pin in coupling assembly to ensure the quality consistency and stiffness uniformity of the pin.
