摘要
冲击摆运动特性研究对于激光推进冲量耦合过程的分析具有重要价值.以实验测量冲击摆运动的角位移为基础,通过不同初始条件下的运动微分方程,分析了数值解的计算精度,建立了合理的阻力模型,描述了冲击摆在激光脉冲瞬间作用下的运动特性.结果表明:数值研究很好地再现了冲击摆运动的实验过程,验证了脉冲激光对光船作用瞬间完成的特性.
The study on movement performance of impact pendulum is of great value to the analysis of the impulse coupling process of laser propulsion. Based on the angular displacement of impact pendulum by experiment measure and movement differential equation under different initiative condition, calculating precision of arithmetical solution is analyzed, rational resistance model is built up and the movement performance of impact pendulum under instantaneous action of laser pulse is described. The result shows that numerical studies primly represent the experimental process of impact pendulum movement and validate the performance that the action of laser pulse to lightcraft is completed instantaneously.
