摘要
讨论了基于系统总质量最优化要求下的固定—固定型无阻尼弹簧质点系统的构造问题,通过求解广义逆特征问题获得了该问题的可解性条件和解的表达式,给出了数值算法和算例。
This paper discusses the optimal design of a fixed - fixed undamped data. The prescribed data involves physical parameters of subsystem and partial mass - spring system from prescribed information of modes. The objective function is ∑ mi. The conditions for the existence of the solution is showed. The expression of the solution and the related numerical algorithm is derived. A numerical example is given.
