Visual Dynamics Simulation For Adapters Separation Of Missile Launching

The process of the adapter separating from the missile plays an important role in the safety and reliability of missile launching, which involves complex dynamics calculations. In order to guarantee the safety of separating the adapter from the missile and successfully launching the missile, this article was concerned with the whole process of the adapter separating from the missile launching system and presented a novel calculation method and visual simulation software to analyze the dynamics process of adapter separation. The dynamics models including the coordinate system, dynamics and kinematic equations, and the forces acting on the adapter are established. The random factors and their distribution law that greatly influence the separation process are analyzed, the confidence intervals of the separation reliability are estimated by using the Monte Carlo method, and an algorithm for calculating the distance between the adapter, missile wing, and tail rudder is proposed. Visual simulation software for analyzing the separation process is designed, which gathers modeling, solving, and analytical processing. Finally, a numerical simulation result is given to verify the validity and correctness of the proposed method and software and analyze the factors affecting the separation reliability of the separating process of adapters for missile launching. The method and software presented in this paper can provide support for the safety design of missile adapter separation.
