| 摘 要： | 基于450条大型运输船舶的船型子样及其快速性能试验数据,应用多元统计回归分析方法,分段研究了大型运输船舶的阻力系数与自航因子的快速估算策略。通过不同船型自变量方案组合的对比分析,得出了影响大型运输船舶快速性的主要船型参数,进而得出了两套阻力系数与自航因子的统计回归表达式,并通过实例验证其正确性。研究成果可用于大型运输船舶的航速快速预报,也为大型运输船舶的快速性能优化指明了方向。

| Abstract: | Based on the performance and propulsion test data of 450 large-scale transportation ships,the statistics and regression analysis method is used for researching on the quick evaluation strategy about the resistance coefficient and propulsion factor.By comparison and analysis with different combined parameters,the principal dimension parameter influencing the performance and propulsion of the large-scale transportation ships is gained,then two suits of expressions about the resistance coefficient and propulsi... |
