Study on Reappearance Technology of Position and Time for Projectile Based on Virtual Reality

The reappearance technology of position and time for projectile based on the virtual reality was studied for making the abstract test data to direct viewing movement and providing the reliable basis to improve the projectile performance further. In the paper, the attitude and position determination method of projectile is introduced in detail, the construction and actuation of projectile model based on the VRML also is introduced, and the simulation was carried on using a group of test data, the correctness of the simulation was confirmed by the image from high speed photography. It is indicated that the reappearance technology of position and time for projectile based on the virtual reality is one of feasible movement simulation methods of projectile, and has good promoted value.
