摘要
起落架是飞机重要承力并兼有操纵特性的机构,在飞机的安全起降过程中担负着十分重要的使命。飞机起落架落震试验系统是开展飞机着陆动力学研究的基础,是飞机起落架设计的关键。为验证多体动力学分析软件LMS Virtual.Lab Motion在民用飞机起落架落震试验仿真上的可行性,基于某型民用飞机主起落架落震试验开展研究,给出了起落架落震试验仿真分析的建模方法。通过仿真结果与试验数据的比较,验证了该方法的正确性和可行性。
Landing gear is an important component of aircraft which supports the fuselage and has a characteristic of control.It plays an important role in the safety of aircraft,especially during the process of landing and taking off.The landing gear drop test is the basis for the study of aircraft's dynamic landing and is the key to the design of landing gear.In order to explore the practicability of multiple body dynamic software LMS Virtual.Lab Motion in landing gear drop test simulation of civil aircrafts,based on a real drop test of one certain type civil aircraft,the procedure of simulation model building is created.By comparing simulation results with experimental data,the correctness and feasibility of the method is verified.
