On The Dynamic Load Identification by Usingof Forward Analysis in Time Domain

Chu Liangcheng;Qu Naisi;Wu Ruifeng(Department of Engineering Mechanics DUT)  
A new analysis method has been provided for dynamic load identification of a discrete system intime domain, it solves the inverse problem by means of Duhamel integral in forward analysis. Basedon the presupposition that the number of measured signals is not less than the number of required iden-tification loads, the proposed method overcomes the error of identification accuracy that is limited bythe number of the measured signals in traditional metheds. Numerical results show that this methodwill obtain accurate solution theoretically if the measured signals will be true.In this paper the SVD(Singular value decornposition) method is applied to solving the conflictingequations system instead of LS(least square)method, this method can obtain the LS solution withleast norm even in that ease, when the rank of coefficient matrix is deficient.
