Laser-driven-flyer-plates techniques have important applied significance on new dynamic high-pressure loading and simulating space particles motion.Kinetic energy numerical calculation of flyer plates based on laser driving is always research hotspot.According to LSDW theory supported by laser,this article analyses detonation-wave pressure expanding during time and space on flyer plates.Then we adopt impulse theory and momentum-Kinetic Energy relationship in order to get flyer-plates kinetic energy equation.Finally,giving aluminium flyer plates an example,we analyzed the laser influence,pulse width,flyer diameter,flyer thickness influence on flyer plates Kinetic Energy in detail.The results indicate that flyer plates kinetic energy increase as laser influence,pulse width,flyer diameter increase and flyer thickness decrease.
