| Abstract: | In this paper,an equation about impact force be- tween two vibrating systems having local deformation is derived in terms of modal analysis theory.The relationship between the impact force and the dynamic behavior of the systems is revealed.Then nu- merical methods for the solution of the equation are proposed and programed for a computer.The impact force between a lumped mass and a sponge-supported steel beam is solved,the result is in good agreement with that from practical test. |
