摘要
激光驱动飞片技术在动高压加载和模拟空间高速粒子运动规律等实验中有重要的应用价值。而激光与飞片的动量耦合模型研究是激光驱动飞片技术的重要内容之一,其实质是激光与物质的作用规律的宏观表征。以激光支持爆轰波(LSDW)理论为基础,建立了约束条件下激光驱动飞片的动量模型,模型考虑了激光功率密度、脉宽、聚焦焦斑、侧向稀疏波、飞片表面气体参数、飞片面积等因素的影响,比较全面地反映了LSDW对飞片的力学作用特性,理论计算结果与参考文献结果吻合较好,误差不超过25%。
Laser-driven flying plates technique（LDFT） is an important and feasible way to load materials and simulate highvelocity motion law of space articles. The momentum coupling model for laser-driven flying plates is one of the important research fields of laser driven flyer plates techniques, whose essence is macroscopical representation of laser-material interaction law. According to laser-supported-detonating-wave（LSDW） theory, this article builds a model on momentum calculation of laser driven flying plates under constraints. Taking into account the factors such as laser power density,pulse width, focus spot area, sparse wave, atmosphere parameters of flying plates surface and flyer plates area, the model demonstrates the action mechanism of flying plates by LSDW theory. Theoretical calculations agree well with the results from reference paper with error less than 25%.
