Abstract： The frequency domain analysis of marine equipment anti-shock capacity is a common engineering evolution method. A finite element model of diesel is established, and modified by the mode experimentation of main components. According to GJB1060.1-91, the shock load of compute model is confirmed based on DDAM method, then the shock response is analyzed on each shock load. Results indicate that the frequency domain analysis of marine equipment anti-shock capacity is an effective evolution method, and this diesel model achieve to the demand of the GJB by the evolution.
