| 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． |
