탄성접촉을 고려한 포신의 동적해석에 관한 연구

초록

This paper deals with a dynamic modeling of artillery system loaded by gun charge explosion during firing condition. Geometric and elastic gun data are used to modify a projectile interaction model. The maximum impact force on gun barrel was 15,000 N and the gun barrel moved about 1.3 m. A cannon ball was presented to travel in the flexible gun, the traveling distance was about 23,000 m, and the angular velocity was about 10 rad/s.
