摘要
起落架是飞机重要的结构之一,在飞机的起飞、着陆以及停放时发挥重要作用。起落架收放系统使得起落架在起飞和降落时能够将起落架收起和放下,有效地减少飞机飞行阻力,提高飞行效益,是起落架的重要功能之一。
本文详细介绍了现代飞机起落架收放系统,并针对A320飞机主起落架收放进行了分析。应用PROE软件建立起落架的主要零部件并装配成系统再仿真起落架收放过程。根据运动原理设计起落架锁机构和收放作动筒运动参数,并且输出了需研究的仿真数据以及运动动画。以此为基础研究起落架收放系统的运动,并且详细分析了起落架收放过程中锁结构和收放作动筒之间的作动关系。
基于PROE软件建立起落架及模拟起落架收放运动,为起落架结构优化和改型设计、收放运动性能分析奠定一定的技术基础,对起落架收放系统的学****有一定的参考价值。本文通过软件调试指出了下一步将要研究的方向,对于起落架收放系统的改进研究有一定的参考价值。

Principle analysis and simulation of the extension and retraction
of the A320 main landing gears
Abstract:
The landing gear is one of the important structures of the plane, when the aircraft takeoff, landing and parking,it plays an important gear system can make the gear up or down during take-off or landing , effectively reduce the flight resistance, improve the efficiency of the flight, is one of the important function of the landing gear.
This paper introduces the modern aircraft landing gear system in detail,analyzes the extension and retraction of the A320 main landing main landing gear parts and assembling them into system was established by Pro/E software as well as simulation the process of landing gear extension and retraction. According to the principle of motion design motion parameters of landing gear’s actuating cylinder and lock mechanism, and output the important simulation data and motion animation. Based on this research, analyzed in detail of the relationship between the closes lock
structure and actuating cylinder in the process of gear system movement.
Based on Pro/E software build landing gear and simulation it’s movement, lay a technical foundation for landing gear structure optimization and retrofit design, performance analysis and movement. It also has certain reference value for the study of landing gear system. Through the software
