Probability Analysis Of The Attacking Attack At The Last End

In order to give full play to the technology advantages of attacking top armor pattern of terminal-sensitive projectile(TSP), and make terminal sensitive projectile function on multiple platforms, it is very high practical and value to study the swept flight assault roof (SFAR) TSP,which can be launched by tank gun etc. Through studying the initial disturbance caused by the motion in chamber and the flight trajectory of SFAR TSP, the factors affecting the hit probability of SFAR TSP, were analyzed, which could provide the reference for the overall design of SFAR TSP.he effect of the structure asymmetry on the initial disturbance of the projectile was studied theoretically. The motion process of SFAR TSP in chamber was modeled by ADAMS software. The influence rules of the changes of mass center location and rotational inertia on the projectile initial disturbance were analyzed, and the force generated by the impact of chamber wall and SFAR TSP was obtained, which could provide simulation data to the stiffness design and the launching safety verification.With the force analysis in exterior ballistics trajectory, the procedure of the SFAR TSP trajectory with 6 degrees of freedom was edited by MATLAB, and the matching degree of projectile speed and rotate speed was calculated and analyzed. On the basis, the influence degrees of initial velocity, fire angle, projectile mass and environmental factors on the hit probability of SFAR TSP were computed based on the Monte Carlo method.The study of the factors influencing hit probability can offer certain references to the design of SFAR TSP, and provide help to the engineering development of SFAR TSP.
