| 摘 要： | 将刚度可靠性设计理论和稳健设计方法相结合,讨论了具有非正态分布参数的梁结构的刚度可靠性稳健设计问题,提出了刚度可靠性稳健设计的计算方法.把可靠性灵敏度融入可靠性优化设计模型之中,将刚度可靠性的稳健设计归结为满足可靠性要求的多目标优化问题.在基本随机参数的前四阶矩已知的情况下,通过计算机程序可以实现具有非正态分布参数的梁结构的刚度可靠性稳健设计,迅速准确地得到具有非正态分布参数的梁结构刚度可靠性稳健设计信息. |
| 关 键 词： | 梁结构 非正态分布参数 刚度可靠性 稳健设计 |

| Abstract: | Combined the stiffness reliability design theory and the robust design method,the reliability-based robust design of beam structure stiffness with non-normal distribution parameters is extensively discussed and a numerical method for stiffness reliability-based robust design is proposed.The reliability sensitivity is added to the reliability-based optimization design model and the stiffness reliability-based robust design is reduced to a multi-objection optimization.On the condition of known first four moments of basic random variables,the respective program can be used to obtain the reliability-based robust design information of beam structure stiffness with non-normal distribution parameters accurately and quickly. |
| Keywords: | beam structure non-normal distribution parameters stiffness reliability robust design |
