摘要
分析现有舰船海况模拟平台指标制定上的不足,提出等效摇摆参数的概念,确定以过载系数相等的等效原则,按照横摇、纵摇、横纵摇耦合分析幅值不变、周期不变、幅值周期改变3种情况下的等效摇摆参数。结果表明,现有舰船海况模拟平台指标产生的过载系数偏小,不能准确反映实际舰船摇摆效果,要产生一致的摇摆效果,舰船海况模拟平台指标必须进行等效换算。
This paper analysed the shortcoming of the index of ship motion simulation platform in existence,introduced the concept of equivalent swing parameters,confirmed that the equivalent principle is they have equal overload coefficient between ship and its simulation platform.Based on the assumed data,some equivalent parameters were studied.Results showed that the index of ship motion should be conversed to the simulation platform to achieve consistent swing effects.
