摘要
本文探讨了用附加已知质量的方法求解有阻尼质量弹簧系统逆特征值问题的可能性。它意味着可以从测得的复频率信息中淬取出系统的结构(物理)参数。而系统的复频率的获得只需在结构上布置一个测点。
The purpose of this paper is finding out an approach to solve inverse eigenvalue problems of damped mass-spring system by attaching known masses. So that the physical parameters of the system can be identified from the com- plex frequency data which are easily obtained with one measuring sensor.
