摘要
在有限条－迁移子结构法的基础上，引入了Riccati变换，提出了有限条－Ric-cati迁移子结构法．计算任意支承矩形弹性薄板在任意激励下的动力响应．把迁移子结构法的两点边值问题转化成两个一点初值问题，克服了有限条－迁移子结构法可能出现的数值不稳定的缺陷，有效的节省了计算机内存，提高了计算精度和计算效率．
In this paper, on the basis of finite strip-transfer substructure method with Riccati transformation, the finite strip-Riccati transfer substructure method is established for calculating forced vibration response of elastic rectangular thin plates. By this method one two-point boundary problem of finite strip-transfer substructure method is converted into two one-point initial values problem. Thus, it not only solves the problem of numerical instability characteristic of the finite strip-transfer substructure method, but saves the memory requirement and computational time of the computer.Meanwhile, the calculating accuracy and efficiency are also improved.
