Finite Element Analysis of Slamming Pressure on the Bow of a 40m Yacht

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 40 m 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.
