摘要
在刚度可靠性设计理论与灵敏度分析方法的基础上,研究了任意分布参数的梁结构刚度可靠性灵敏度分析问题,提出了刚度可靠性灵敏度分析的计算方法,给出了可靠性灵敏度的变化规律,研究了设计参数的改变对梁结构刚度可靠性的影响,为任意分布参数的梁结构刚度可靠性设计提供了理论依据。
Based on the stiffness reliability-based design theory and sensitivity analysis method, the stiffness reliability-based sensitivity analysis of beam structure with arbitrary distribution parameters is extensively researched and a numerical method for stiffness reliability-based sensitivity analysis is presented. The variation regularities of reliability sensitivity are obtained and the effects of design parameters on reliability of beam structure are studied. The method presented in this paper provided the theoretic basis for the stiffness reliability-based design of beam structure with arbitrary distribution parameters.
