Research of initial disturbance of rocket in lagrange 拉格朗日方法建模下的火箭弹起始扰动研究
A method to study random factor ' s effections on initial disturbance of projectile 随机因素对弹丸起始扰动影响的分析方法
The primary work of this thesis is as follow : ship motion is an important factor which effected missile initial disturbance 作为影响舰载导弹发射初始扰动的重要因素,对舰艇运动规律的研究非常重要。
One of the inequalities is that the initial disturbance amplitude is more than a critical value , and the other is that the frictional coefficient is more than another critical value 初始扰动振幅大于某一临界值; ( 2 )摩擦系数大于某一临界值,前者对后者有很强的约束。
The introduction of nonlinear advection into the model weakens the intensifying of maximum tangential wind with relative to the initial disturbance azimuthally wave numbers and intensity Ssbyt和台风强度影响的研究似二波分布扰动使tc强度的增幅并没有实际二波扰动的增幅大。
The main conclusions show as following : 1 the effects of propagating vortex rossby waves on tc intensity change are relative closely to the position , the size and intensity of the initial disturbance 主要结果可归纳如下: 1涡旋rossby波传播对热带气旋强度变化的影响,与初始扰动相对涡旋中心的位置、初始扰动尺度大小及强度等关系密切。
Launch process of missile , especially initial disturbance , is an important direction of launch dynamics . with the development of compute simulation and launch dynamics , much technology and method has been researched in the area of launch process 导弹发射过程,特别是导弹的初始扰动是发射系统研究的一个重要课题,随着计算机仿真和发射动力学的发展,对导弹发射过程的研究也有许多不同的途径和技术。
The controlling force developed by the jets is working at the beginning of the initiative trajectory ( 0 . 385 - 3 . 385s ) to control the attitude of the projectile to keep its axis on the direction of launch - direction , so as to reduce the effect of initial disturbance 控制力由喷流作用力产生,在主动段的初始段( 0 . 385 3 . 385秒)控制弹体的姿态,使弹轴维持在初始方向上,从而减少初始干扰,减小落点散布(飞行时间约170秒) ,提高精度。
