摘　　要：针对飞机防滑刹车系统的特点,在Labwindows/CVI环境中利用OpenGL开发工具设计实现了飞机刹车过程的视景仿真。采用OpenGL和3DSMAX相结合的方法逼真、准确地完成了飞机模型设计;通过二次曲面模型、二维贴图、光照以及粒子系统等技术形象地虚拟出了飞机刹车的仿真环境;结合Labwindows/CVI中的图形控件和OpenGL函数实现了多窗口视景;采用RS-485总线技术解决仿真数据的实时通信。通过雨天刹车系统的仿真实例可看出,该系统较好的满足了飞机防滑刹车系统仿真的可视化要求,为飞机防滑刹车系统提供了逼真、实时的视景仿真环境。Aiming at the characteristic of braking system of aircraft, OpenGL was applied to realize the visual simulation system for the braking process in LabWindows/CVI. OpenGL was combined with 3DSMAX to design the aircraft model realistically and exactly. The simulation environment for the braking of aircraft was virtualized by conicoid model, planar paste, illumination and particle technology. Then the graph control of LabWindows/CVI and function of OpenGL were utilized to realize multiple scene view. RS - 485 was applied to realize real - time communication. Through the simulation for the braking of aircraft in rainy environment, this system meets the visualization need for the simulation of aircraft＇ s braking system well. Virtual scene view has provided vivid real - time simulation environment for the simulation of the braking system of aircraft.
