An experimental study on the measurement of the aftereffect kinetic energy of spherical fragment penetrating steel armour by ballistic pendulum 用弹道摆测定球形破片侵彻钢质甲板后效动能实验研究
Transient and average thrust are two important performance parameters of pulse detonation engine. The principle and system structure of direct measurement method and indirect measurement methods ( including thrust wall pressure integral method and ballistic pendulum method) are introduced. 针对脉冲爆震发动机瞬时推力、平均推力测量问题,介绍了直接测量法和间接测量法(包括推力壁压力曲线积分法和抛物摆法)的测量原理及系统构成。
Using ballistic pendulum test, the transients of impact forces, displacements and energy absorbing are estimated. 利用冲击摆锤试验,测定了冲击力、冲击点位移以及能量转换的瞬态值。
