江海直达船鞭击振动分析

对江海直达船首部砰击引起的鞭击振动进行了仿真分析,采用瞬态动力学模态分析法,计算过程中考虑附连水的作用。分析参数有砰击压力峰值和连续砰击次数,对比分析仿真结果,得出不同压力峰值和连续砰击次数的影响规律。

Whipping Analysis of River-to-sea Ship

Taking simulation analysis on whipping of River-to-Sea Ship induced by bow slamming,using the modal analysis method on the transient dynamics,the role of additional water was considered on the calculation.The analysis parameters are ：magnitude of peak pressure and number of continuous impact.With the comparison of simulation results,we can obtain the rules of magnitude of peak pressure and number of continuous impact,which can provide constructive suggestions for River-to-Sea Ship design.
