由于卫星载荷的功率受限, 使得天基高能激光的方案只能处于构想, 为了增加天基激光对空间碎片清理的可用性, 研究了连续波1 064 nm激光辐照铝金属的热分布, 分析了连续波作用下的热力效应, 建立了激光作用金属材料的热效应解析模型并数值模拟了其温度场分布, 并以此为基础论证分析了低功率密度的连续波激光对铝金属结构热破坏作用的可行性, 在低功率大光斑的连续波辐照条件下, 工作状态的铝金属结构存在热和力学的综合破坏模式, 即利用低功率密度的连续波激光同样可以实现对空间碎片的清理。

Due to the limited power of satellite loads, the space-based high-energy laser scheme can only be in the idea. In order to increase the space-based laser availability of space debris clean-up, the heat distribution of 1 064 nm continuous wave laser irradiation aluminum metal is researched. Through analyzing the continuous wave action on the thermal effect, the analytical model of the heating effect of metal materials and the numerical simulation of the temperature field distribution are established. On this basis, the feasibility of the low power density of the continuous wave laser heat damage on aluminum metal structure is analyzed. Under the condition of continuous wave laser irradiation at low power large spot, the working state of aluminum metal structure exist the comprehensive damage model of heat and mechanics. The space debris clean-up can be realized using the continuous wave laser with low power density.
