| 摘 要： | 建立以支撑(位置、刚度)和截面几何特性为设计变量,以结构重量极小化为目标,以动强度可靠性指标和固有频率为约束的管道动力优化模型.针对某类管道,对支撑位置、刚度和管径进行优化分析,得到了支撑、截面参数和管道动力特性之间的关系.计算结果表明此优化方式是合理有效的.经过优化,提高了首超可靠度,减轻了结构重量,降低了动应力,增强了管道的抗振能力.

| Abstract: | Aim.The introduction of the full paper reviews a number of relevant papers in the open literature,points out what we believe to be their shortcomings,and then proposes the design mentioned in the title,which we believe is new and better than previous ones and which is presented in sections 1 through 3.Their core consists of: A dynamic optimized model of pipeline under constraints on dynamic strength reliability and on natural frequency was established,where the support(location,stiffness) and cross-sectiona... |
