| Abstract: | Based on the applying research of the theory of modal force method, a kindof assembly method, the main force method is put forward, Several examples arepresented which nearly represent all the normal linkage means of substructures. Uponcomparing the assembly results from using main force method with those fromtheoretical means, it is turned out that the correctness of the applying, that is applyingmain force method to the assembly of modal force matrix, is verified, the difficulty ofprogramming with modal force method is reduced, and the reliable means of usingmodal force method is provided. |
