Research on Application of Functional FMECA in Reverse Engineering Optimization

This paper studies how to apply the functional FMECA-a reliability analysis method in the reverse engineering process to make up for the shortcomings in reliability design. Analyze the implementation process of traditional reverse engineering; aiming at the shortcomings of the reverse engineering process such as the lack of reliability design, etc, optimize the implementation process. Failure mode effects and criticality analysis (FMECA) is one of the major methods used in reliability analysis, in which the functional FMECA is one branch that can analyze potential failure modes and possible effects and criticality of failures in the conceptual design phase of products. It can find out the potential weaknesses of the design process to facilitate the improvement of design before the determination of product structure, which is an effective method to guarantee the quality of reliability design. Applying the functional FMECA-a reliability analysis method in the reverse engineering, we can find out the potential weaknesses of the design process in the early phase of imitation. On this basis carry on the design improvement, and realize the synchronization of reverse design and reliability design, thus ensuring the reliability of the product. Finally, with the reverse engineering of a missile as an example, the functional FMECA is conducted, and the combination of reliability design and performance design is realized according to the influence between the functional FMECA and the design of products.
