At last , the researchers discussed and analyzed the results of the simulation contrastively . firstly , according to the conditions of the aircraft being researched , differential coefficient equations of the aircraft during its symmetric landing are established systemically in this paper 文章的主要内容包括:以某多轮多支柱飞机的起落架为例,依据该起落对称着陆的实际情况,系统地建立了该飞机的全机着陆动力模型以及飞机主起落架数学模型。
Up to now , the dynamic simulation for aircraft landing and taxiing by the software adams based on the full aircraft model has not been found . in this paper , dynamic analysis for landing gear landing and taxiing is conducted for a large transportation aircraft with a post nose landing gear and two truck main landing gears . a dynamic analysis model of the landing gear and a full - scale aircraft model used in the simulation are developed by applying dynamics basic theory 论文以我国某大型运输飞机起落架为研究对象，应用动力学基本原理，基于adams aircraft模块建立了起落架着陆动态性能分析模型以及由机身、前起落架缓冲支柱、前起落架机轮、主起落架缓冲支柱和主起落架机轮五个子系统构成的全机模型，进行落震、全机着陆与滑跑动力学仿真。
According to the six different loading process of axle , it adapts ansys software to do numerical simulation . then it does large amount of analysis to the calculation results . 11 draws a rather reliable conclusion , and it provides a theoretical reference for the experiment of the stress distribution of axle model . at the same time , we have done electric experiment according some loading process 本文系统地阐述了对主起落架的车轴模型的简化、前处理、有限元建模、加载并求解和后处理的过程，并且针对车轴六种不同的载荷状况，运用ansys软件进行了数值模拟，对计算结果进行了分析，得出了比较可靠的结论，为车轴模型的应力场测试提供了一个参考依据。
Secondly , a full - aircraft assembly model in software adam is defined , which includes an airframe subsystem , a strut subsystem of the nose landing gear , a wheel subsystem of the nose landing gear , a strut subsystem of the forward main landing gear , a wheel subsystem of the forward main landing gear , a strut subsystem of the after main landing gear and a wheel subsystem of the after main landing gear 在adams软件中建立了一个由机身、前起落架缓冲支柱、前起落架机轮、前主起落架缓冲支柱、前主起落架机轮、后主起落架缓冲支柱和后主起落架机轮七个子系统构成的全机模型,并对该模型进行了对称着陆仿真分析。
