设计制作并试验研究了利用电磁成型机电源的电弧炮,k结果表明弹丸速度随电源能量的增加和熔丝质量的减少而增大。在10kJ的能量下把弹丸加速到了近1km/s。在该速度下的大颗粒(φ4钢球)以及小颗粒(φ0.1金钢砂)和微粒(微米级Cr2O3抛光粉)与经固溶处理和电场时效的1420铝合金权的撞击试验表明,粒子注入深度与粒子大小相当。大颗粒穿透1.8mm板材时在其轨迹旁材料中的塑性变形成波浪型分布,而小粒子注入时表现为粒子旁材料的塑性变形很小,且因弹性回复粒子在正前方与被注入材料间存在间隙。
Design and experimental study of the use of electromagnetic forming machine arc gun, k results show that the projectile speed increases with the power of energy and reduce the quality of the fuse. The projectile is accelerated to nearly 1 km / s at a energy of 10 kJ. The impact test of the large particles (φ4 steel ball) and the small particles (φ0.1 grit blast) and the fine particles (micron Cr2O3 polishing powder) at this speed with the right solution treatment and the electric field aging 1420 aluminum alloy showed that, Particle injection depth and particle size quite. Large particles penetrate the 1.8mm plate material in its trajectory plastic deformation into a wave-shaped distribution, and small particles injected into the performance of particles next to the material plastic deformation is small, and elastic recovery particles in front of the material being injected There is a gap between.
