摘要：

An efficient mechanical structure reliability analysis method was proposed based on combination of evidence theory and approximation model technology. Firstly, a corresponding mathematical model of reliability analysis was established based on evidence theory. Then, an approximate model of limit state functions was constructed by radial basis function. Local-densifying samples were used to improve the fitting accuracy of the approximationg model. Finally, the approximation reliability analysis problems were solved by the first-order approximation reliability analysis method, and the belief measures and plausibility measures of mechanical structure reliability were obtained. Computational results demonstrate that the method may ensure the accuracy of the calculation results, and improve the computational efficiency. © 2020, China Mechanical Engineering Magazine Office.
