基于Flash CS3的B737飞机起落架刹车系统模拟仿真

起落架刹车系统能在飞机着陆时配合扰流板与反推装置增大飞机的阻力,使之迅速减速,减小滑跑所需距离。运用Flash CS3软件对B737飞机液压动力刹车系统工作原理进行模拟仿真,用逐帧动画和补间动画两种方法将液压的流动方向以动画形式直观展现出来。详细分析了在人工刹车的工作方式下正常刹车、备用刹车和蓄压器刹车三种形式的工作过程。将两种仿真方法进行对比,结果表明:逐帧动画制作简单但表现形式欠佳,补间动画虽过程复杂但结果更加直观形象。针对B737飞机起落架刹车系统工作原理的动画模拟仿真,对刹车系统的学习、维修、研究和改进等具有一定的参考价值。

SIMULATION OF B737 LANDING GEAR BRAKING SYSTEM BASED ON FLASH CS3

The landing gear brake system can cooperate with the spoiler and thrust reverser to increase the resistance of the aircraft and make it decelerate rapidly and reduce the distance needed for taxiing.The working principle of the hydraulic braking system of the B737 aircraft was simulated based on Flash CS3 software.The flow direction of the hydraulic pressure was intuitively displayed with Flash by using frame-by-frame animation and tween animation.The working process of normal brake,spare brake and accumulator brake under the working mode of manual braking was analyzed in detail.The two simulation methods were compared,and the results show that the frame-by-frame animation is easier to make,but the form of expression is not so good.Although the tween animation is complicated,the results are more intuitive and visual.The animation simulation of B737 aircraft landing gear braking system has a certain reference value for the study and maintenance,research and improvement of brake system.
