大型水陆两栖飞机地面滑跑稳定性分析与仿真

起落装置直接关系到飞行器的起飞与着陆安全,是其重要部件和系统之一。大型水陆两栖飞机的起落架设计需在空气动力学与水动力学领域得到协调,是一个更为复杂的动力学问题,同时也是当前大型飞机研制中亟待解决的问题之一。基于多体动力学理论与LMS Virtual.Lab仿真环境,建立某大型水陆两栖飞机地面滑跑过程的动力学模型,通过对其地面对称滑跑等情况的仿真计算,着重对滑跑过程中的航向稳定性进行分析,实现水陆两栖飞机对称滑跑动力学分析与仿真。

Analysis and Simulation of a Large Amphibian Aircraft Taxiing

The landing gear system works in concert with the safety of the aircraft′s take off and landing directly,therefore it is one of the most important parts and systems of an aircraft.The landing gear design of an amphibian aircraft need to coordinate aerodynamics and liquid dynamics.It is a complicated dynamical problem,and it is the problem which is faced during the process of the large amphibian aircraft design nowadays.Depending on multi-body dynamical theories and the simulating plate of LMS Virtual.Lab,the dynamical model of a large amphibian aircraft taxiing process is proposed.By simulating the model,the analysis of the heading stability during taxiing is conducted.The dynamical analysis and simulation of a large amphibian aircraft′s heading taxiing is achieved.
