摘要： 铝打磨过程采用湿式除尘避免了粉尘爆炸，但是带来氢气爆炸危险.提出一种基于WBS-RBS-BN的铝合金打磨湿式除尘系统氢气爆炸事故的评价方法.通过WBS-RBS将湿式除尘系统的工作和风险因素进行分解，得到耦合矩阵，画出氢气爆炸事故故障树.将故障树转化为贝叶斯网络，计算得到爆炸事故发生概率为5.54E-07.通过基本事件后验概率计算结果，明确易导致事故发生的基本事件，指导安全管理.

Abstract: Aluminum grinding process using wet dust removal system can avoid dust explosion，but there is a risk of hydrogen explosion accident. The research on the risk assessment of aluminum wet dust removal system and safety management is limited. A WBS-RBS-BN evaluation method for hydrogen explosion accident is presented. The coupling matrix and hydrogen explosion fault tree could be identified by decomposing WBS-RBS the risk factors of wet dust removal system. The fault tree could be changed into Bayesian networks， and the explosion probability is 5.54E-07. After calculating the posterior probability of basic events， basic events leading to the accident are clarified and identified. The study is helpful for the guidance of safety management.

Key words: WBS-RBS, BN, wet dust removal system, aluminum alloy dust, hydrogen explosion accident
