| Abstract: | Techniques from the probabilistic perturbation method and the Edgeworth series technique were employed to present a practical and effective method for the reliability optimization design for back-axle housing with arbitrary distribution parameters of vehicle on the condition of known first four moments of basic random variables. The theory formulae of reliability optimization design for back-axle housing with arbitrary distribution parameters of vehicle were obtained. The respective program can be used to obtain the reliability optimization design information of back-axle housing with arbitrary distribution parameters accurately and quickly. The results demonstrate that the method proposed in the paper is a convenient and practical one on computing reliability and designing back-axle housing with arbitrary distribution parameters. |
