摘要
驾驶舱视觉舒适性会直接对驾驶员产生影响,可能引起驾驶员视觉疲劳和操作失误,对飞机驾驶的安全性和驾驶员的身体健康非常不利。采用日光眩光概率(DGP)、亮度对比度(LR)和人眼垂直照度(EV)指标,对不同的季节、日照时间和天气条件下的飞机驾驶舱进行视觉舒适性的仿真研究,形成数据库。结果表明:该方法可在飞机设计阶段对飞机驾驶舱的视觉舒适性进行有效地评估,研究结果可为飞机驾驶舱防眩布置及照明设计提供一定的指导。
The visual comfort property of airplane flight deck is of immediate impact on pilot. It could cause the pilot visual fatigue and misoperation, and be bad for the health of the pilot and safe driving. Three indicators, namely, daylight glare probability（DGP）, luminance ratios（LR） and vertical illuminance at the eye level（Ev ） are used to） analyze the optical simulation result in flight deck and study on the visual comfort under the different seasons, times, sky conditions, and the database about comfort is established. The result shows that this meth od can estimate the visual comfort of flight deck effectively in the stage of airplane design. Research results can provide some guiding significance for antidazzle design of airplane flight deck.
