| 摘 要： | 回顾了船舶兴波阻力计算的发展历程,采用Michell积分计算赛艇兴波阻力是比较理想的。通过对两条双人赛艇和一条单人艇的计算及分析表明:赛艇的兴波阻力随速度的增加会出现阻力的"峰点"和"谷点"。较高的速度有利于专项技术的训练,中等速度有利于专项力量的训练,速度太低,训练就不会达到很理想的效果。

| Abstract: | The development history of the calculation of wavemaking resistance of the rowing shell was reviewed. It is ideal to apply Michell integral to calculate wavemaking resistance of the rowing shell. The result of the calculation of two double rowings and one single rowing indicates that wavemaking resistance will appear "the peak point" and "the lowest point" of the resistance with the (increase) of velocity. Higher speed will make for special technical training while medium speed will be in favor of special strength training and lower speed will not bring ideal training (result.) |
