Abstract

The invention discloses a strong laser driven explosion and impact effect test platform which comprises a drive system, testing environments, a measurement system and a control system, wherein the control system is respectively connected with the drive system, the test environments and the measurement system. Through an integrated design and development of different test environments, the test platform realizes multiple laser driven explosion and impact functions and has openness; and meanwhile, through coordination and cooperation of multiple high-speed and high-resolution rate testing means, a plurality of physical fields (speed, pressure and image) are measured in real time, and a laser drive explosion and impact test process can be more completely characterized.

Description

technical field [0001] The invention relates to the field of explosion and impact effects, in particular to a strong laser-driven explosion and impact effect test platform. Background technique [0002] Laser-driven explosion and impact is the development direction of explosion and impact dynamics research, and it is the frontier field of mechanics. Explosion and impact research carried out by laser drive has obvious advantages in terms of efficiency, safety, and precision measurement technology. In particular, laser-driven explosion and impact can obtain ultra-high pressure (above the GPa level), ultra-short pulse (ns level), high impact velocity (km / s level) and ultra-high pressure that conventional explosion and impact methods cannot achieve. A high strain rate (above the order of 106 / s) is an indispensable means for carrying out cutting-edge scientific and technological research. [0003] The strong dynamic loads generated by laser-driven explosions and impacts have th...
