Abstract Based on the shortcomings of traditional FMEA in analyzing problems and finding solutions， an innovative design method integrated with fishbone diagram， FMEA and evolution laws was proposed. This method used the hierarchical analysis of fishbone diagram to assist FMEA fully excavate possible failure modes， then analyzed failure modes according to the standard expression of FMEA and determined the Risk Priority Number（RPN）. By adopting evolution laws， the method can solve the failure problems effectively and efficiently. This paper also verifies the feasibility of this integrated method with an example of vibration damping design on rail track．

集成鱼骨分析与进化法则的产品失效预测及问题求解
基于传统FMEA在失效问题分析与解决方面的不足，提出了一种集成鱼骨图、FMEA和进化法则的创新设计方法．利用鱼骨图层次化分析辅助FMEA全面挖掘可能发生的失效模式，按照FMEA的规范表达分析失效模式并确定风险优先指数RPN，然后运用进化法则针对失效问题进行有效的解决，提高了解决问题的效率．最后通过铁路减振的示例验证了该集成方法的可行性．
