Solving the Equivalent Function of Failure Mode Based on Multiple Correlation

To solve the problem of equivalent functions of failure mode and low computational efficiency, the coefficient expression of equivalent functions has been derived based on equivalent principle. The concept of multiple correlation was introduced to the reliability analysis of failure mode, the correlation problem between several components and a component has been explained rationally. The display recursive expression of equivalent functions involved two-dimensional integral computation has been given. The high calculation accuracy and efficiency of solving recursive equivalent functions has been indicated according to numerical results.
