摘　　要：针对波音737NG系列飞机的内外侧主轮,通过其受力情况、所处环境及飞行员驾驶水平等多方面的分析,结合某航空公司B737NG系列飞机机轮更换情况数据库,总结出内外侧主轮的损伤差异性,并对提升内外侧主轮使用安全性及经济性提出优化建议,进而降低航空公司运营成本。研究发现:内侧主轮受力较大,主要受到着陆时的冲击力和机身垂直重力的影响,典型的损伤模式是胎肩磨损加剧;而外侧主轮则受到横向荷载的影响较大,典型损伤模式是胎面的磨损和胎肩剥离。总体而言,内侧主轮比外侧主轮更易磨损,数据库的统计结果证实了这一结论。This paper focuses on the inner and outer main wheels of the Boeing 737NG family aircraft.Through analysis of their force conditions,environment and pilot skill levels,in conjunction with a certain airline's database on the replacement of B737NG family aircraft wheels,it summarizes the diferences in damage between inner and outer main wheels,and puts forward optimization suggestions to improve the safety and economy of inner and outer main wheel usage,thereby reducing the operating costs of airlines.The research results show that the inner main wheel is subjected to greater force,mainly due to the impact force and fuselage vertical gravity during landing,which increase the possibility of shoulder wear.The outer main wheel is subject to greater lateral load,and the typical damage modes are peeling at the tire shoulder and tread wear.In general,the inner main wheel is easier to be worn out of limit than the outer main wheel,and the statistical results of the database confirm this conclusion.
