Analysis of parameters causing jamming in strut-type landing gear shock absorbers

研究了支柱式飞机起落架的结构类型与卡滞特性。基于经典卡滞分析理论,构建了起落架卡滞特性分析的数学模型,并导出了起落架上下轴承支反力与地面载荷的函数关系,进而建立了卡滞计算模型,分析了支承轴套摩擦因数、支承轴套间距、起落架安装倾角及扭力臂安装角度对卡滞因数的影响。

This paper investigates the structural types and sticking characteristics of strut-type aircraft landing gears.Based on classical stick analysis theory,a mathematical model for analyzing the sticking characteristics of landing gears is constructed,and the functional relationship between the upper and lower bearing reaction forces of the landing gear and the ground load is derived.Furthermore,a stick calculation model is established to analyze the effects of bearing sleeve friction coefficient,bearing sleeve spacing,landing gear installation inclination angle,and torque arm installation angle on the stick coefficient.
