穿浪双体船耐波性能预报方法研究
Study on Prediction Methodology of Seakeeping for WPC
-
摘要: 基于修正的切片理论的Seakeeper软件可以用来在方案设计阶段对穿浪双体船进行耐波性的理论预报,平均阻力增量除了在Fr>0.6后误差很大外,其他耐波性指标包括纵摇有义值、升沉有义值和垂向加速度有义值在Fr〈1.0的范围内与船模试验结果相比有较好的精度。Abstract: Software Seakeeper is based on the modified strip theory. This paper with a WPC as example, calculated the seakeeping with Seakeeper. At range of Fr<1.0, the calculation precision of main indexes of seakeeping qualities are acceptable at project design, except added resistance at Fr<0.6.
