冲击环境预报是爆炸载荷作用下舰船动力学分析的重要手段，其预报结果可为舰上设备提供关键的抗冲击设计输入值，根据船体结构和设备安装特点设计了动力学分析模型并进行了水下非接触爆炸载荷下的冲击环境预报，系统地研究船体板架结构、设备基座以及设备本身的冲击环境预报动力学建模方法，分析不同建模方式对设备冲击环境预报结果的影响，归纳典型结构的动力学建模原则，研究结果对舰船设备的冲击环境预报具有借鉴意义。
The shock environment prediction is an important means of ship dynamic analysis under the explosion load and the prediction results are the key shock resistance design input values of the ship equipment. According to the ship plate-girder structure and equipment installation characteristics, the dynamic analysis model was designed and the shock environment were predicted under the non-contact underwater explosion. The modeling methods of shock environment prediction for hull plate-girder structure, equipment foundations and the equipment itself were systematically studied and the influence of different modeling methods on the prediction results of shock environment were also analyzed. The principles of dynamic modeling of typical structures were summarized at the end. The research can be applied to the shock environment prediction of the ship equipment.
