摘要
提出了一种基于优化原理建立的动态聚缩模型．该模型以期望的动态特性作为约束条件，将聚缩模型结构物理参数的求解问题转化为特定约束下的优化问题，这样计算精度较高，能满足多阶模态分析的要求．
A dynamic condensation model based on optimization principle is presented.Theanticipated dynamic characteristics are taken as the constraint factors in this model.Thenthe solution of the structure physical parameters of the moldel can be modified to the opti-mization under specific constraints. The numerical computation shows that the condensationmodel can meet the requirements of the engineering precision.
