Research On A Launch Method Of Missile Leaving Guide Rail Simultaneously And Its Dynamics Characteristics

Based on the design theory of launcher and the dynamics of launch,the paper discusses the preliminary design and dynamic response differences of three types of guidance,such as the method of missile leaving guide rail non-simultaneously,the method of missile leaving guide rail non-simultaneously with adapter,the method of missile leaving guide rail simultaneously and so on.On this basis,a new synchronous orbital detonation method is proposed,which is based on the combination of the adapter and the directional support.It is of great theoretical significance and engineering application value.First,the rocket launch mode and the research method are described in a comprehensive and systematic way,and the specific research contents and research methods are clarified.Then,the multibody dynamics model for complex dynamic response analysis of the launching process is established based on the theoretical basis of launch dynamics and the calculation of multibody dynamics.The model is based on the multi-rigid-body model,and the interactions between the components of the transmission system are investigated by the contact model based on the Hertz collision theory and the flexible connection model based on the spring damper.The dynamic response characteristics of three kinds of inclined launch modes,which are compared and analyzed.The response characteristics of three kinds of inclined launch modes are analyzed from the missile sinking amount,the attitude angle of disturbance and the impact on the follow-up flight,and other aspects of the focus of assessment.Considering the small variation of the attitude angle of he method of missile leaving guide rail simultaneously and the advantage in bearing,damping and separation of adapter,this paper presents a new type of launch method combined with the adapter and the directional support.Its typical structural components were designed,and the dynamic response was analyzed.The results show that this kind of launch method has the characteristics of both small initial detentions and the characteristics of simple and reliable separation,which is of great value to the design of future inclined launching devices.
