基于Virtools的外弹道仿真研究与设计

摘要

介绍了一种基于Virtools的外弹道的简单仿真方法.首先建立弹丸运动的数学模型,给出直角坐标系下弹丸质心运动方程组.然后在Virtools中利用VSL语言编程设计了解算模块,通过龙格库塔法对弹道方程进行解算,并将解算得到的坐标数据进行存储.最后通过在Virtools中相应模块的连接实现了在Virtools中对弹丸外弹道的简单仿真.%Introduced a simple method of trajectory simulation based on Virtools.Firstly, the mathematical model of pill is designed and the equations of trajectory in the rectangular coordinate system are discussed.Secondly,the calculation module is designed based on VSL and the trajectory equation is solved using Runge-Kutta method. And the data obtained is stored in the array.Finally .the simple trajectory simulation is achieved by connecting the corresponding BB in the Virtools.
