摘要
本文介绍了飞机研制中的结构动力学设计问题,包括结构多频优化设计及其程序系统SDD1以及结构频响优化设计及其程序系统SDD2,并给出了算例。
In this paper, structural dyanmic design problems in the development of aircraft, including structural multifrequency optimal design with program systems SDD 1 and structural frequency response optimal design with program system SDD 2 are introduced. There are three parts of contents; 1)analysis of natural frequency (or response) for primal structure; 2)sensitivity analysis of structural parameters for natural frequency (or response); 3) Optimal design on structural frequency (or response) with SUMT. The example is provided in text.
