摘　　要：采用粗糙集理论来进行装载机故障知识的获取,给出了装载机诊断推理的策略和流程。该方法提高了诊断系统的容错性,为在不完备信息下的装载机故障诊断提供了一种新的思路。实例诊断结果证明了该方法的有效性。A approach of loader＇s fault diagnostic knowledge acquisition was put forward, and then the inferential strategy and process of loader＇s fault diagnosis based on the rules got by knowledge acquisition were described. The approach improves the fault-tolerance performance of fault diagnosis system, and presents a new idea to loader fault diagnosis on the incomplete symptom information. Examples show that the proposed approach is very effective.
