摘要
阐述了以大系统理论部件建模为基础的轮式起落架仿真建模方法。通过分析机轮的运动特点 ,介绍了轮胎、减震支柱、前轮转向操纵系统和刹车系统的模型 ,研究了作用于起落架上的力、力矩及其传递过程。最后 ,通过计算和结果分析 ,证明该模型是正确的。
This paper describes a modeling method of the wheeled landing-gear on the basis of the theory of huge-system's components modeling. It analyzes the characteristics of wheel motion, introduces the models of the tire, shock strut, nose-wheel turning control system and break system models and studies their forces, moments and transitive procedures on the landing-gear. Finally, the correction of model was certificated by calculating and results analyzing.
