Abstract:Techniqu from the probabilistic perturbation method and constraint random direction method are employed to present a practical and effective method for the reliability optimization design for the back-axle housing of vehicles on the condition of known probabilistic characteristics of original random variables. The theoretic formulae of reliability optimization design for the back-axle housing are obtained. A practical program can be used to obtain the reliability optimization design parameters of the back-axle housing accurately and quickly.
Keywords:back-axle housing  reliability optimization design  probabilistic perturbation method  constraint random direction method
