国内外对飞机地面载荷的研究主要是针对每个起落架的总载荷,很少见到具体针对起落架各机轮载荷分配的研究报道,而工程上又迫切需要相关的针对飞机起落架机轮载荷分配的计算分析方法。大型飞机的起落架大都采用多轮多支柱的的布置形式,机轮载荷的分配问题变得愈加突出。文中建立六轮小车式起落架的车架动力学平衡方程,探讨机场不平度对六轮小车式起落架前、中、后机轮载荷分配的影响,提出六轮小车式起落架机轮载荷分配的计算分析方法,并以波音777飞机为例进行计算,验证文中所提出方法的有效性和可行性。
In the domestic aod the abroad, the research on landing gear wheel load distribution mainly focuses on the total load. Few studies have yet to be seen in the light of specific landing gear wheel load distribution but there are urgent needs of wheel load distribution calculation method for aircraft landing gear. The study what impact the roughness that is the major factor of the airport runway has on wheel load distribution and establishes calculation and analysis methods for the load distribution of the six-wheeled landing gear. The effectiveness and feasibility of the method presented are demonstrated by the example of wheel load distribution calculation of Boeing 777 aircraft.
