摘要:
为了分析环境温差对瞄准镜光学系统的影响机理,研究光学透镜在径向和轴向温差作用下的变形规律,该文首先利用传热学和光机系统设计知识进行理论分析,然后利用ANSYS对径向、轴向温差分别为1 ℃、2 ℃、3 ℃、4 ℃、5 ℃、-1 ℃、-2 ℃、-3 ℃、-4 ℃、-5 ℃时的各透镜进行了仿真分析。得到各透镜的瞬态温度场分布和总应变云图,并绘出总应变随径向、轴向温差的变化曲线。仿真结果表明:透镜温度场沿径向和轴向成梯度分布; 径向温差最大总应变出现在透镜高温侧的边缘处,轴向温差最大总应变出现在透镜高温侧的中心位
Abstract:
In order to analyze the influence of environmental temperature difference on sight optical systems and study the rule of deformation of optical lens under the action of radial and axial temperature difference,the deformation of optical lens is analyzed theoretically by the heat conduction theory and optical mechanical system design method,the lens under the radial and axial temperature difference of 1 ℃、2 ℃、3 ℃、4 ℃、5 ℃、-1 ℃、-2 ℃、-3 ℃、-4 ℃、-5 ℃ are simulated and analyzed respectively.The transient temperature distribution field and total thermal strain of the optical lens are got and the curve of total strain is drawn out with the radial and axial temperature difference.The analysis results show that the temperature field changes in the radial and axial directions gradually; the maximum radial total strain is on the edge of higher temperature side,the maximum axial total strain appears in the center of the higher temperature side; when the temperature difference is the same,the influence of the axial temperature difference is bigger than the radial temperature difference; the maximum total strain are changing with temperature differences linearly.
