摘要
采用瞬态动力学有限元软件DYTRAN,对舰船设备在水下爆炸冲击波作用后的动态响应进行了研究。介绍了如何利用DYTRAN软件模拟水下爆炸过程,并提出了优化计算文件来节约计算时间提高解题效率的方法。最后,对某舰船主机的隔振装置的抗冲击性能进行了分析。
Principles and methods for dynamic response computation of ship to underwater explosion are introduced in this paper. First, how to simulate explosion underwater by DYTRAN software. Second, The cost-effectiveness of the analysis can be increased by modifying document of computation. At last, an example about the computation of shock response of marine diesel engine resilient mounting system is given in order to show the validity of the method.
