【摘要】 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。 本文对导弹发射动力学进行了研究，主要分两大部分，舰载发射和地面发射。对每种发射方式，采用了不同的分析建模方法，针对实际模型进行了仿真及结果分析。本文所作的主要工作为： 1．对舰艇的运动进行了分析。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。给出了谱分析法求解舰艇运动的方法。 2．采用了动静法的描述形式建立了舰载导弹在发射段的数学模型，分别给出了导弹相对发射坐标系的相对运动模型和导弹在地面坐标系下的绝对运动模型。 3．建立了地面发射的数学模型，考虑了导轨弯曲和发射装置振动等扰动因素。为了便于分析各参数对导弹运动特性的影响，同时建立了不考虑发射装置影响的简化模型。 4．给出了导弹安全发射不与发射装置碰撞的判断条件。 5．建立了与以上发射动力学模型相应的仿真模型，并对仿真结果进行了分析，所得结论对战术导弹发射系统的设计具有一定的参考价值。 本文建立的模型对其它型号的导弹也适用，只需对导弹发动机参数、定向器有关参数、发射架在舰艇上布置参数和浪谱参数等输入参数进行修改，就可得到不同型号导弹在发射段的运动参数。更多还原

【Abstract】 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.In this thesis, the model of launch dynamics is researched. It consists of ship-based launch and ground-based launch. The different model is established for different style of launch and the numerical are carried out. The primary work of this thesis is as follow:Ship motion is an important factor which effected missile initial disturbance. So it is very necessary to research ship motion. The models of ship motion are analyzed under random wave action. The method of applying frequency analysis theory is proposed to resolve the problem of ship motion.The mathematic models of ship-based missile in launch period are established. These models consist of relative motion in launch-fixed coordinate and absolute motion in earth-fixed coordinate.The mathematic models of ground-based missile in launch period are established. It is effected by the factor of disturbance such as guiding rail sprctrum, vibrant launch device.Based on these aspects mentioned above, the safe launch problems are discussed. The judging condition is proposed concerning whether the missile will collides with launch device in launch process.At last, digital simulation system is developed to simulation the process of launch. The results of simulation are analyzed in detail.The models which are established in the thesis are applicable to other style of missile. Input parameters of engine, guiding rail, launch devices to model, you can gain the result what you need.更多还原
