摘要
阐述结构动力学优化设计的研究背景和意义。根据实践,扼要介绍近十年作者在结构动力学设计研究方面取得的若干新近展,内容包括,随机激励下以均方响应为约束的设计方法、结构动力学形状优化、结构动力学拓扑优化、动力学设计约束的性质和解的存在性以及结构控制一体化优化设计,并对进一步的研究工作做简要展望。
The research background and significance of structure dynamic optimization are described briefly. According to the authors' research practice, a series of recent progresses on structural dynamic design is introduced as follows: the design method with the mean square response as the constraint under random excitation, structural dynamic shape optimization, structural dynamic topology optimization, the property of the constraints and the existence of the optimal solution, the integrated optimization of structure and control. A prospect for the future development is presented briefly too.
