摘要
建立艇体扰流的数值模型,通过数学分析、建模及仿真计算分析研究艇速对水下航行体水平发射的影响;研究分析水下航行体水平发射斜出水时轨迹参数受艇速影响时轨迹参数的变化趋势。仿真结果表明艇速的影响主要改变水下航行体的轨迹、切向速度、z轴流体力矩及周围区域的流动形态,艇速主要改变所受的流体俯仰力矩。
Through building the mathematical model of hull disturbed flow, logistic calculation and simulation, the study on submarine velocity is to find the effects on horizontal launching of an underwater vehicle. The changing trend of trajectory parameter is gained by analysis of submarine velocity. The results shows that the trajectory curve, tangential velocity, the moment of liquid in Z direction and flow pattern around, is changed. The submarine velocity main changes the moment of liquid elevation angle.
