Abstract

Equilibrium elbow is a key mechanical component in the self-propelled artillery system and the reliability analysis of the component is necessary to the safety of the whole system. In this paper, the equilibrium elbow model is established to analyze the reliability and reliability sensitivity of arbitrary distribution parameters. Three main failure modes and the times of loading action have been taken into account when analyzing the reliability sensitivity. Numerical method for reliability calculation is presented based on four moment method and the reliability sensitivity model of mean and variance values with random structural parameters were established. Based on the results of the reliability sensitivity analysis, reliability robust optimization design has been studied to enhance the reliability of equilibrium elbow and decrease the reliability sensitivity of mean and variance value. Application of the proposed approach could provide a practical routine for mechanical optimization and design.
