基于DDAM方法的船舶推进系统冲击响应仿真

Simulation of Shock Resistance Capability of Ship Propulsion System Based on DDAM

简要介绍动态设计分析方法(DDAM),采用DDAM方法对某船舶推进系统进行抗冲击分析。通过计算得到船舶推进系统三向冲击应力响应云图,总结得出船舶推进系统的抗冲击特性和规律。

The dynamic design analysis method（DDAM） was introduces briefly.The shock resistant performance was analyzed by DDAM for a ship＇s propulsion system.The stress distribution diagram was obtained for the ship propulsion system.The anti-concussion characteristic and rule of ship propulsion system were summarized.
