Abstract

The filtering frequency of shock response is difficult to study due to its obvious character of transient and non-linearity in the course of shock response of warship. So far there is no standard or uniform method of choosing filtering frequency for anti-shock research. The specific analysis method and criterion is provided in this article by using impulse information variance of shock response as the method of choosing filtering frequency. The shock response filtering frequency of the shipbuilding structure and equipment has been analyzed by our method. The results show that the shock response filtering frequency is equivalent as for the same shipbuilding structure but different as for the same ship equipment in the different distance of explosion.

Key words
