摘要
本文探讨了用附加已知质量的方法求解无阻尼质量弹簧系统的逆特征值问题的可能性.它意味着可以从测得的频率信息中淬取出系统的物理(结构)参数.而系统的频率识别只要求在结构上布置一个测点.
The purpose of this paper is to find out an approach of inverse eigenv-alue problems of undamped mass-spring system by using an attached lump of known mass.It means that the physical parameters of system can be est-imated from frequecy data which are easily obtained by using one sensor
