Research On Virtual Experiments Of Mass Point Trajectory Law Of Motion

In recent years, the application of virtual reality technology becomes more and more popular in our country, and the scope that used this technology is also getting more and more broad, introducing the virtual experiments technology in the training system is an important development direction, Because it both has vivid, the lifelike virtual environment and may avoid kinds of dangers which can happen in real testing and operation, at present, we did not have mature mass point trajectory virtual experiment system both in domestic and foreign.This paper studies the law of motion of the mass point trajectory, analyzes the shell's movement equation set that under certain supposition condition and under the influence of the external condition, establishes the simulation system's mathematical model, and solves the simultaneous differential equation set using the numerical value method, use 3DS max to establish the model and the scene that the system needed, realizes the trajectory demonstration and shell body's movement under the computer environment combined with the graph image display technology, and the use of multi-thread programming makes system's operating efficiency to enhance greatly.The paper uses Visual C++6.0 development kit, Mercury Corporation's 3D interactive graph development toolbox Open Inventor6.0 and its IVF(Interactive Visual Framework) frame.The virtual experiment system of trajectory law of motion has been designed and realized.
