摘要

摘要: 单自由度轨迹机构具有单输入多分量输出的特性.传统机构运动可靠性理论对各输出分量误差独立建模以建立机构运动的可靠性分析模型,该分析模型不能反映机构运动的整体失效情况.为此,提出了一种基于圆形区域的误差模型和可靠性分析模型,并采用1阶可靠性算法对可靠性分析模型求解.为提高模型求解精度,提出采用遗传算法并结合序列二次规划的混合优化算法实现最大可能点的求解.数值实例验证了该方法的有效性.

Abstract: The single freedom degree mechanisms have a feature with single-input and multi-output. In traditional mechanisms reliability,the analysis model for kinematic reliability is created with each coordinate direction component. The present model can not embody the overall failure conditions of mechanisms. Finally,the motion error model and the analysis model for kinematic reliability are presented based on the circular area. The first order reliability method(FORM) is used to solve the present model. To improve the calculation accuracy,a hybrid optimization algorithm which includes genetic algorithm(GA) and sequential quadratic programming(SQP)algorithm is presented to find the most probable point. A numerical example is given to demonstrate the effectiveness of the present method.
