Numerical simulation of the initial disturbance influencing on intensive degree

摘要

With regard to the research object of a kind of rocket projectile, the influence of gun muzzle vibration by jet impact is considered. Both the launching dynamic model and the intensive degree model are founded. The circumstances of firing time partition for 0.3s to 0.5s are simulated numerically. The results are compared, and the way to improve the intensive degree is presented as well.
