A new impulsive load identification method in time domain is proposed in this paper in which the dynamic loads are assumed to be linear functions within a time-step and the precise time-integration method is used. In this new algorithm, a precise load identification model is constructed which is not based on the recursion— chain computational format, so the problems of being sensitive to the initial values and the error cumulating are well solved. Furthermore, the TSVD regularization technique is used to overcome the influences of ill-conditioned matrix and measuring noise. Nu-merical example shows the effectiveness of the proposed algorithm.
