摘要:
为了研究艇艏横倾时的砰击状况，采用数值模拟的方法对一艘长40 m钢制游艇的艇艏砰击性能进行了分析.在验证有限元方法模拟船舶入水砰击的基础上，利用ANSYS/LS-DYNA软件建立船艏二维有限元模型，分析了游艇不同入水速度和横倾角对艇艏砰击压力的影响规律，数值模拟结果为预报艇艏的砰击压力状况提供依据，为游艇的结构设计提供参考价值.
Abstract:
Slamming is harmful to ships and the status of bow slamming in heeling is rarely studied.Because yacht heeling will inevitably occur when navigating in storm，it is necessary to be studied the effect of bow slamming.The slamming performance on the bow of a 40m steel yacht was studied using numerical simulation method.Based on the validation of ship analysis model established to simulate the slamming process in twodimensional，the influences of slamming pressure with different speeds and angles on yacht bow have been analyzed and exhibited by employing LS/DYNA finite element method.The comparison results can be a reference to predict the time-varying dynamics of bow slamming pressure，which is of great importance for the structure design and operating performance of yacht.
