摘要
为对三体船的纵摇与升沉运动进行分析,将三维面元法用于三体船在波浪中的纵摇和升沉计算。依据Rankine源格林函数,基于有航速势流理论建立理论计算模型和数值计算方法,对数学三体船型纵摇、升沉运动响应进行计算,并对计算结果规律进行分析。同时,还对其数值进行模型实验验证。根据计算结果,针对侧体布局对三体船在波浪中纵向运动的影响进行了分析。
In order to analyze the pitch and heaving motion for trimaran on waves,the three dimensional panel method(3DP) was used.Based on Green Function of the three dimensional Rankine source,the theoretical model and numerical calculation procedure for wave motion potential flow theory with ship speed were developed,and calculating the motion response of pitch and heaving of Wigley trimaran.And the law of the calculation results was analyzed and compared with the model test results.Furthermore,the influence of side hull position on the longitudinal motion of trimarans on waves was analyzed.
