| Abstract: | 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. |
