Research and Design of Trajectory Simulation Based on Virtools

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.
