Abstract： According to the convolution integral relationship between the impact force and response, the paper discrete the convolution equation and change the integral equation to simple algebraic equation. Due to the force identification problem is a well-known ill-posed problem, and the solution is unstable. In order to obtain the stable solution, an improved regularization technique is used in this paper. Numerical tests are made to verify the proposed method, and the results are compared with the ones identified by the traditional Tikhonov regularization method, they show the proposed method gives better results than the traditional Tikhonov regularization method.
