弹丸在水介质中的运动特性仿真研究

It is very difficult to accurately study the law of projectile motion, projectile velocity, vacuole characteristic and other correlation characteristics with the classical theory, as the projectile moves in the water. This article uses the transient state mechanical analysis software simulated the law of submarine projectile motion from the initial movement to the stabilized state and the formation mechanism of vacuole which is around the projectile; direct-viewing obtained the trajectory variation law of projectile in the process of movement as well as the pressure, density variation characteristic of waters around the projectile. By the simulation result, the projectile velocity attenuation law mathematical model is established; the law of projectile motion is analyzed. This article provides the reference for the future optimized underwater projectile contour design and the trajectory characteristic analysis and calculations.
