射击仿真过程中实体碰撞命中检测模型研究

针对射击仿真过程中空间实体碰撞命中检测问题，在已建立的动力学和运动学模型解决了实体位置、姿态及运动趋势解算基础上，提出了考虑对抗双方实体空间占有区域因素，建立目标几何等效体壳体方程，分析了碰撞发生的必要条件，建立了实体碰撞检测模型，可解算最初碰撞命中点参数，并为之后的毁伤描述提供必要的参数条件。

Study on Model of Entities Collision Hitting Detection in Shooting Simulation

It is studied the problem of collision checking in shooting simulation based on dynamics and kinematics models established before. Entities space occupancy region factor of both sides is taken into account. The target equivalent bend surface equation is established, the collision genesic necessary condition is analyzed and the entities collision checking model is set up. The model can not only figure out original collision hitting point parameters, but also provide necessary condition for damage describe later.
