Visual Simulation And Damage Effect Evaluation Of Ground-to-ground Fuze Warhead Coordinatio

The defense performance of ground armored targets continues to improve in today’s large-scale land operations.The terminal sensitive ammunition,as a smart and intelligent ammunition that can achieve long-range strikes and destroys against the top of the target,has always been valued in various countries.In this thesis,a set of visual simulation and damage evaluation system is designed around the fuze-warfare coordination process of the doublewing type non-umbrella terminal sensitive projectile on the ground tank target.The content is summarized as follows:(1)Based on the multi-rigid body theory,the aerodynamic force analysis of the doublewing umbrellaless terminal-sensitive projectile is carried out,and its flight trajectory and steady-state scanning motion model are established,and the scanning coverage area of the terminal-sensitive projectile is theoretically analyzed according to its scanning parameters.Then,based on this theory,based on the Matlab/Simulink modular method,the parameter changes and scanning area during the movement process are simulated and verified,and the initial condition parameters are provided for the visual simulation model.(2)For a certain main battle tank target and explosively formed warhead,a threedimensional model of the tank target is established and vulnerability analysis is carried out.The damage mechanism of the warhead is theoretically analyzed and simulated,and then the explosive formed warhead and the damage probability and damage evaluation model of the tank are established..(3)Based on the Unreal Engine 4,the visual simulation of the fuze and warfare coordination process of the double-wing umbrellaless terminal sensitive projectile is realized,and the basic environment,the establishment of the 3D model of the bullet and the realization of the ray detection,collision detection and other fuze warfare models are completed in turn,and the virtual scene is established.The visual simulation model of the movement of the midparachute double-wing terminal sensitive projectile and the demonstration of the whole process of damage to the tank target,and the damage effect is evaluated.
