| 摘 要： | 为研究舰载火箭由于舰船摇摆而产生的过载对其发射时初始扰动产生的影响,设计虚拟正交试验来仿真计算舰载火箭在不同状态下的初始扰动,并通过多因素极差分析得到海况、迎浪角、发射仰角和发射装置在舰船甲板的安装位置4种影响因素对舰载火箭初始扰动的影响程度.仿真结果表明,4个因素对初始扰动的影响都不可忽略,对初始扰动影响程度由重到轻依次为发射仰角、海况、迎浪角和安装位置.

| Abstract: | It is observed that the overload on a ship-borne rocket excited by ship swaying motion affects the initial disturbances during launching process,and the overload coefficient is affected by multiple factors.Virtual orthogonal experiment was designed in order to simulate the initial disturbances of ship-borne rocket in different states.Influenced degree of initial disturbances,which was caused by sea condition,trim angle,launching angle of elevation and location of the launcher on the ship deck,was obtained b... |
