摘　　要：针对单个诊断方法故障信息的模糊性和分散性,建立了基于证据理论的综合诊断方法。其中融合策略灵活多变,且模型已由单故障模式推广到多重故障模式,使之更适应实际工程诊断需要。最后应用其对某转子系统故障进行了诊断,结果表明方法行之有效。Directing to the faintness and dispersiveness of fault data of single diagnosis method, a comprehensive diagnosis method based-on evidence theory was established. The diagnosis tactic was adaptive, and the model was generalized from single fault mode to multiple faults mode. So it is more applicable in practical fault diagnosis. This method was applied in fault diagnosis of a rotor machine, the results show it is effective.
