摘要
在稳定可靠性设计理论与灵敏度分析方法的基础上,研究了压杆稳定可靠性灵敏度设计问题.提出了稳定可靠性灵敏度设计的计算方法,给出了压杆可靠性灵敏度的变化规律,研究了设计参数的改变对压杆稳定可靠性的影响,为压杆稳定可靠性设计提供了理论依据.
Based on stable reliability-based design theory and sensitivity analysis method, research on stable reliability-based sensitivity design for compressive bar is carried out and a numerical method for reliability-based sensitivity design is presented. The changing rules of reliability sensitivity are obtained and the effects of design parameters on reliability for compressive bar are studied, which provides theoretic basis for reliability design for compressive bar.
