|
摘要
针对火炮发射实验具有不可重复性、周期长、人力耗费大、技术要求高等问题,本文提出了火炮外弹道虚拟仿真方法.本文根据火炮射击过程特点,分析火炮质点外弹道方程组,建立弹丸外弹道运动过程数学模型;结合虚拟现实技术及Unity3D引擎,采用3ds Max建立火炮和弹丸实体模型,以C#作为开发语言对弹道进行计算,控制弹丸运动,实现对火炮发射过程的仿真模拟;通过仿真实验数据与弹道表数值分析比较表明,本方法不仅在视觉上能够较好的展现火炮发射和弹丸的飞行状态,同时误差控制在可接受范围内,为火炮外弹道的研究提供了便利.
Aiming at the problem of non-repeatability, long period, high labor cost, and high technical requirements of the artillery launching experiment, this work studies the virtual simulation technology of artillery external ballistics.According to the characteristics of the artillery firing process, it analyzes artillery particle exterior trajectory equation set and establishes the mathematical model of the external ballistic motion process of the projectile. Combining virtual reality technology and Unity3 D development engine, 3 ds Max is used to build the artillery and projectile solid model, and C# is used as the development language to calculate and control the ballistic motion of the ballistics, and realize the analogue simulation of the artillery launching process. According to the analysis of the simulation data and the firing table, the simulation experiment is not only visually showing the flight state of the artillery launch and projectile, but the deviation is within the acceptable range, which facilitates the research of the external ballistics of the artillery.
