摘　　要：为了更好地研究水下垂直电磁发射系统装置在水下工作的特点,首先推导了描述系统控制体运动状态的动力学方程和连续性方程;然后,分析了流体控制体间流量计算及窄缝隙泄漏量计算等关键问题的研究方法,构建了能够模拟装置水动力特性的水动力解析模型。研究表明:通过水动力解析模型仿真得到的在电磁力作用下动子的运动轨迹和装置关键环节的压强,与水下垂直电磁发射实验测量得到的相应数据相比误差较小,验证了该水动力解析模型的准确性和有效性。Aims at the working environment of the underwater vertical electromagnetic launch system device,firstly,the dynamic equations and the continuity equations describing the motion state of the control volumes in the system were derived.Secondly,the key problems such as the flow calculation between fluid control volumes and the leakage flow in narrow gaps were analyzed.Then,the hydrodynamic analytical model was constructed to simulate the hydrodynamic characteristics of the device.The results show that under the action of electromagnetic force,there is little error between the mover′s trajectory,the pressures of the device′s key parts and the corresponding data measured by underwater vertical electromagnetic launch experiment.So,the accuracy and applicability of the hydrodynamic analytical model were verified.
