激光器与轨道的相对位置对动态加热的影响

 通过分析光束入射的角度因子将激光器在地平面上的安放位置进行分类，采用了几何分析和数值模拟的方法，探讨了聚焦激光束在加热运动圆柱体过程中，为了达到一定的加热功率水平和能量水平以取得最好的加热效果而应采取的措施，即应当以激光垂直入射的轨道点为中心，以激光的有效工作时间为取值范围，并参考大气对激光能量的衰减，相对于轨道选取适当的距离进行加热。该研究从理论上说明了激光器与圆柱体运动轨道的相对位置对激光动态加热的影响可以看作一个优化问题，存在最优解，进而对于合理使用激光器进行动态加热具有参考价值。

Effect of laser setup position relative to trajectory on dynamic heating

According to the incidence angular factor of the laser beam, the locations of the laser setup above the ground are classified. The methods of geometrical analysis and numerical simulation are used. It is indicated that when a focused laser beam heats a flying cylinder, for the sake of the best heating effect, as to achieve enough heating power level and energy level at the same time, the trajectory point when the laser beam can irradiate the cylinder perpendicularly should be selected as the heating center, the effective work time of the laser should be regarded as the heating time range, and the laser setup should be placed at a proper distance from the cylinder at the very trajectory point. It is found that the problem of effect of relative position between laser setup and trajectory on dynamic heating is an optimal problem, which can give a good reference for using a laser setup properly on dynmic heating.
