The Dynamic Simulation Of Multi-body Separation Between Capsule And Vehicle On Water Surface

The research of dynamic simulation technology provides many references for the control of flight path and flight attitude of vehicles after leaving the capsule.For a long time,a lot of experts and researchers have made plenty research on the launching and separation technique of underwater launched vehicle,making a lot of achievement.With the existing experience and achievements,the motion process and forces acting during the separation being analyzed,the dynamic model of the separation of vehicle and capsule on water surface is established.According to the separation process and the forces acting during the time,a simulation model and a computing method,based on the six degrees of freedom,are established in MATLAB/simulink.Meanwhile,considering the stiffness and the damping of the adapters,the model which can analyzes and computing the forces of adapters is established.Based on the strip theory,the hydrodynamic calculation module is also established.By the specific simulation example,the validation and correction of the simulation model,adapter model and the hydrodynamic model can be proved.Eventually,the comprehensive comparation of simulation results and experimental results is conducted,which proves the two results fit well.With the comparation,the effectiveness of the simulation and the computing method can be proved.In summary,a dynamic simulation method of the separation between the capsule and the vehicle is provided in the paper,which is efficient and corrective.The research gives a convenient and effective platform to the further research of the separation on water surface.How specific parameter can influent the separation results is shown in this paper.Further,the separation results of specific parameter are predicted,which helps forecast the results and optimize the separation design.Modules with other functions can be added to the model to improve the simulation,making the whole progress of the separation be simulated and predicted.
