摘　　要：潜射导弹无动力运载器弹道散布特性是导弹后续弹道和运载器分离体水下散布的重要影响因素,决定其散布的主要因素有初始弹道参数和海洋环境扰动等。建立了运载器空间运动数学模型,利用数理统计中的正交试验法安排实验,对不同工况下运载器上浮弹道进行仿真,通过极差分析确定影响因素的主次关系,利用方差分析法和F检验确定影响因素的显著性。仿真结果表明:横向海流对弹道散布半径影响显著,绕x和y轴的初始角速度及横向海流对位移影响不显著。研究结果可以为弹道规划和运载器加工制造提供一定参考。The trajectory distribution of submarine-launched unpowered missile carrier is the key influencing factor of missile＇s trajectory and the underwater distribution of the separated objects; its main influencing factors are initial trajectory parameters and disturbance of ocean environment. This paper establishes the space kinematic mathematical model, uses mathematical statistics orthogonal experiment to arrange the test and simulate the upward trajectory in different working conditions. The relationship between primary and secondary is found by range analysis and the significant and non- significant influencing factors are analyzed by variance analysis. The simulation results shows that horizontal currents is the significant influencing factor on trajectory distribution radius; initial x or y angular velocity and horizontal currents are the non-significant influencing factors on carrier＇s displacement. The result can be used as a reference in ballistic programming and carrier manufacturing.
