摘要:通过“人机料法环”五个方面对故障进行分析和排查,旨在研究汽车起重机中长臂超载10%工况下,转台出现回转异响情况的故障因素和具体原因,为快速排除故障提供理论依据。试验结果显示,通过“人机料法环”法进行转台异响故障检测和排查,最终确定故障是因为转台局部强度不足引起的,通过局部加强有效的解除了这一问题,并在后续的生产装配中有效的借鉴该经验进行结构改良,避免同一问题的发生。

Abstract:In this study, five aspects of the analysis and investigation on the fault by human material, aims to study the automobile crane arm 10% overload conditions, turntable failurefactors rotary noise conditions and the specific reasons, and provide a theoretical basis for the rapid troubleshooting. The result show that, forthe turntable abnormal sound fault detection and investigation by"human material ring" method, finally determine the fault is because theturntable local strength caused by inadequate, through local strengthen effective relief of this problem, and in the subsequent assembly of effective reference the experience of the improved structure, to avoid the occurrence of the same the problem. 
Key words:truck  crane;turntable;fault
