| Abstract: | The reliability optimization design method of the multi|leaf spring with different thickness is discussed. Techniques from the second moment method and constraint random direction method are employed to present the practical and effective method for the reliability optimization design for the multi|leaf spring of vehicle on the condition of known probabilistic characteristics of original random variables. The respective program can be used to obtain the reliability optimization design information of the multi|leaf spring accurately and quickly. |

| Keywords: | multi|leaf spring different thickness reliability optimization design second moment technique constraint random direction method |
