Sensitive To Play At The End Of The Whole Ballistic Motion Simulation And Virtual Reality Technology Research

Based on the research background of anti-Terminal Sensitive Projectile (TSP) warning system, regarding a typical foreign TSP model as the research object, the theoretical analysis, numerical calculation and image simulation were combined to research the whole trajectory motion rules and visualization of TSP.The structures of TSP in the different motion stages were established. Respectively, the movement process and stress characteristics were detailed analyzed and the dynamic models of four-degree-of-freedom of projectile flight, six-degree-of-freedom of TSP in the decelerating and rotating stage and seven-degree-of-freedom of two rigid body of TSP in stable scanning stage was developed.Based on Matlab/Simulink modular method, the projectile flight and its deceleration trajectory model were brought forward. The variation of the height, attitude, falling velocity, rotating speed with time and motion trajectory were obtained. Based on the Adams software, the dynamic simulation of TSP in stable scanning process was carried out and the falling velocity, rotating speed, scanning angle and scanning trajectory were obtained through the simulation. Additionally, the factors which affected the stable scanning process were analyzed respectively.Based on the Matlab and VR virtual reality technology, a virtual scene of the whole trajectory motion of TSP was established, and a real-time motion process was showed in a virtual scene by the Simulink blocks interactive control. The result can provide technical support for development, confrontation and tactical training of TSP.Finally, the work was summarized, and the existing problems and the direction for further study had be pointed out.
