为解决眩光问题,对飞机座舱眩光分析方法进行研究。针对飞机座舱视环境分析方法与实际情况存在较大差距,初步设计阶段无法较为真实的体现飞机座舱在各飞行阶段的视觉环境与光污染问题,提出了一种飞机座舱风挡反射眩光分析评估方法。以视光学理论和光线追踪算法为理论基础,利用视觉仿真软件,建立能够模拟接近真实人眼视觉感受的座舱视觉仿真环境,并通过实际应用获得了夜航风挡反射眩光的验证结果与实际情况进行对比。经实验表明:该方法可以有效的对驾驶舱可能产生的风挡眩光进行分析,判断反射眩光出现的区域,并对结构优化方案进行评估。
To solve the problem of glare, the cockpit glare analysis method is studied. There is a big gap between the visual analysis of aircraft cockpit visual environment and the actual situation. The preliminary design phase can not reflect the visual environment and light pollution of the aircraft cockpit in each flight stage. A method for the analysis and evaluation of the cockpit windscreen reflective glare is proposed. Based on the theory of optical optics and ray tracing algorithm, the visual simulation software is used to establish the cabin visual simulation environment that can simulate the real human visual perception. The verification result and actual situation of the night glare windshield reflective glare are obtained through practical application Compared. The experimental results show that this method can effectively analyze the possible windshield glare in the cockpit, determine the area where the reflected glare appears, and evaluate the structural optimization scheme.
