Abstract: Based on the reliability design theory and sensitivity analysis method, the reliability sensitivity of the mechanical elements is extensively discussed and a numerical method for reliability sensitivity design is presented. The variation regularities of reliability sensitivity are obtained and the effects of design parameters on reliability of the mechanical elements are studied. The method presented provided the theoretic basis for the reliability design of the mechanical elements.

Key words: Sensitivity, Arbitrary distribution parameters, Mechanical elements, Reliability design
