Optimization of structure response under vibrafuge environment

摘要: 文章以结构的安装角为设计变量，根据结构安装位置的合理性来确定设计变量的约束条件。以结构关键部位的加速度均方根值作为目标函数，建立了随机振动-加速度复合载荷作用下基于安装角的某结构响应优化模型。应用ANSYS软件中的参数化设计语言（APDL）实现了离心场中结构随机振动响应对安装角度的灵敏度分析及优化。优化后的结构振动响应降低了。

Abstract: An optimized model of a structure under vibrafuge environment is built with the fix angle as the design variable. At the same time, the rationality of the fix position is used as the restrictive condition and the RMS value of the acceleration at key points is used as the objective function. The parameter design language (APDL) of ANSYS is applied to perform the sensitivity analysis and the optimization of the structural vibration response under the centrifuge field. The vibration response is obtained after the optimization.
