摘要

摘要: 为研究圆柱型浮标在波浪作用下的运动响应, 分别采用基于势流理论和数值波浪水槽的浮标运动仿真方法对同一浮标模型进行仿真, 并与试验结果进行对比。结果表明, 对于垂荡运动, 2种方法的求解精度均较高。对于纵摇运动, 基于势流理论的方法预报规律趋势正确但定量误差较大, 其优点是所需计算资源较少, 可用于方案初步设计; 基于数值波浪水槽的方法求解精度较高, 但所需计算资源较多, 能够指导浮标精细化设计。

Abstract: To study the motion response of cylindrical buoys induced by waves, the same buoy model is simulated by using two buoy motion simulation methods based on respective numerical wave sink and potential flow theory, and the results are compared with the sea trial data. Comparison shows that: 1) both methods have high solution accuracy for heave motion; 2) for the pitch motion, the method based on potential flow theory gives a correct prediction trend but with low accuracy, however, this method has the advantage of requiring less computing resource, so it can be used for preliminary design of the program; and 3) the method based on numerical wave sink has high solution accuracy but requires more computational resources, so it can used to guide fine design of buoys.
