Launch Dynamics Of Tactical Missile And Simulation

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.
