摘　　要：万向电动叉车是一种新型的电动叉车,其可靠性的高低直接关系到能否安全运行。在对万向叉车系统故障概率分析的基础上,将模糊数学和故障树分析方法相结合,建立了万向电动叉车系统的故障树模型,并进行了定性和定量的模糊分析。根据分析结果,确定了系统的薄弱环节。Muhidirectional electric forklift is a new kind electric forklifts. Its reliability has directly effects on whether the forklift can work safely or not. The fault tree is set up by the combination of analytical approach of fault tree and fuzzy mathematics, based on analyzing the fault reliability of the electric forklift system, and the qualitative and quantitative analysis are provided. According to the results , the weak link of the electric forklift system is defined.

关 键 词：万向电动叉车 故障树 模糊数
