【摘要】 发动机异响是汽车发动机故障诊断的难点,本文基于模糊综合评价诊断方法,建立了发动机异响的模糊综合诊断模型,并开发了计算机辅助诊断系统。实验证明,发动机异响的模糊综合诊断模型充分考虑了实际诊断中的各种因素,开发的辅助诊断系统可以为检测诊断人员指明方向,提高异响故障诊断的工作效率,具有一定的应用价值。更多还原

【Abstract】 It is difficult to diagnose that engine abnormal noise. Based on the fuzzy diagnosis theory, the fuzzy diagnosis model for engine abnormal noise was constituted. Simultaneously, the computer aided diagnosis system was designed. The test results show that the fuzzy analysis methods is very available to diagnose the engine abnormal noise. The detection direction can be indicted by the aided diagnosis system. The work efficiency is improved, and it’s application valuable.更多还原
