Abstract:
The initial disturbances of the rocket weapon system have great impact on its fire intensity,so it is a key parameter for the rocket structure design.In this paper,the relationship between the initial disturbance and the stiffness of the rocket launch system is studied through analyzing the formation process of the initial disturbance of the rocket weapon system.It is found that the excessive stiffness of structures above the landing gear of the rocket causes the structure deformation of the launch system and changes the shape and pattern and the law of the vibration of the rocket.On this basis,the matching of the initial disturbance and the stiffness of the rocket launch system is analyzed.The conclusions are drawn that,in order to control the initial disturbance of the rocket weapon system,the reasonable stiffness of the launch system should be determined by reducing both the deformation of the launch system and the initial oscillating angular velocity of the rocket simultaneous during the design of rocket structures.
