Abstract:To solve the problem in the development process, the wedge screw nut products are developed to meet more complex and more demanding environment. In view of the possible failure modes, the failure analysis is carried out with reliability evaluation process and theoretical model. The life evaluation analysis is carried out with the performance index. The reliability evolution method of the wedge screw nut is proposed and the evaluation results are verified through the ultimate performance test and the life test.
