摘　　要：水下高速运动体可利用前置涡轮传感器来测量其自身运动速度。建立了水下测速涡轮传感器的动态方程,并分析了其在稳定加减速下的响应规律。利用高速水洞设备,设计了加减速的动态过程实验,并对实验结果进行了分析。理论分析和实验结果表明:动态模型与实验结果基本吻合,动态下的运动规律与稳态变化规律基本相符。与静态测量值相比,此水下涡轮测速方案在加减速过程中存在动态误差,其中加速过程误差较大,在实际测量中需要修正。Underwater high-speed moving body can use pre-turbine sensor to measure its own velocity of movement.Dynamic equations of underwater turbine velocity measurement sensor is established,and response rules under steady acceleration and deceleration are analyzed.By using high-speed water tunnel equipment,dynamic process experiments of acceleration and deceleration are designed,and then experimental results are analyzed.Theoretical analysis and experimental results show that dynamic model and experimental results are consistent,dynamic movement rule is agreed with steady-state variation rule.Compared with static measurement value,there are dynamic errors in this underwater turbine speed measurement program in process of acceleration and deceleration,and during acceleration process,the error is large,which requires correction in actual measurement.
