摘要

为优化丢手释放接头的结构强度和重量,提出以应力和质量为目标函数的多目标优化设计方法。将响应面设计方法与有限元数值分析结合,建立了应力和质量关于结构参数的响应面模型,分析了参数间的交互效应。基于响应面模型,通过多目标优化分析获得了释放接头的最佳结构参数配置。优化后的结构应力下降19.5%,而质量增长较小。数值及实验验证表明,优化后的结构安全可靠。所提优化设计方法结合了响应面原理、有限元数值分析和实验测试,可为类似机械或工程结构的设计提供参考。

Abstract

In order to optimize the structural strength and weight of the release joint,a multi-objective optimization design method with stress and mass as objective functions was proposed.In this paper,the response surface methodology combined with finite element numerical analysis was used to construct the response surface model of stress and mass respectively with respect to structural parameters,and the interaction between the parameters was analyzed.Based on the response surface models,the optimal structural parameter configuration of the release joint was obtained by multi-objective optimization analysis.The stress of the optimized structure decreased by 19.5% with a slight increase in mass.Numerical and experimental verification shows that the optimized structure is safe and reliable.The proposed design method,which combines the response surface methodology,finite element numerical analysis and experimental testing,can provide reference for the design of similar mechanical or engineering structures.
