起落架系统是飞机重要承力并兼有操纵特性的机构,其包括动力学、控制、液压等系统。在严重影响飞机安全的起降着陆过程中,担负着十分重要的使命。以典型民用飞机起落架收放系统为研究对象,分析其动力学行为,采用LMS Virtual.Lab Motion和LMS Imagine.Lab AMESim软件进行起落架收放动力学仿真,研究负载对起落架收放的影响以及机构间摩擦力对收放性能的影响。结果表明:模型能在规定时间内收起,负载对收放有明显影响。
Landing gear system is an important bearing capacity of the aircraft and both maneuvering characteristics of the system, including the dynamics, control, hydraulic systems. In the landing and landing processes that seriously affect the safety of the aircraft, they have a very important mission. Taking a typical civil aircraft landing gear retractable system as the research object, the dynamic behaviors of the landing gear system were analyzed. The landing gear dynamics simulation was carried out by using LMS Virtual.Lab Motion and LMS Imagine.Lab AMESim software to study the effect of load on landing gear retraction As well as the friction between agencies on the retractable performance. The results show that the model can be stowed within the specified time and the load has a significant impact on the stowage.
