摘要
基于两栖车阻力产生的机理,提出了一种"改进叠模"航行阻力计算方法.以某履带两栖车为例,分析了其航行阻力的特性、尾部顺流段对航行阻力计算中流场的影响、车体表面动压力变化,获得了两栖车航行阻力成分构成,计算结果与拖曳模型试验数据基本吻合,表明用该方法可以有效分析两栖车的航行阻力.
Based on happening mechanism of amphibious vehicles, a calculation method of "improved multiple models"for research on resistance ingredient and characteristics is proposed in this paper.Flow field influence in calculation of resistance for body multiple model section and dynamic pressure variation are analyzed.Resistance ingredient of amphibious vehicles is obtained. The model test results show that the method is effective.
