| Abstract: | To raise the synthesis efficiency and computation accuracy of mode synthesis (MS) , dividing of system components , choosing of mode - function and determining of number of degree - of - freedom( DOF) of system are studied. And emphasis is laid on the effect upon the system computation accuracy by choosing power series as component shape functions. |
