起落架的性能对整机的安全性和舒适性具有真接的影响。以国产在研某型飞机转弯系统为研究对象,通过Virtual.lab和Imagine.lab联合仿真的分析方法对前起落架转弯系统进行仿真与分析,并通过敏感性分析确定起落架前倾角、轮间距、稳定距和轮胎垂直刚度等参数对起落架最大静转弯力矩的影响。分析结果表明:起落架前倾角对前轮最大静转弯力矩影响最大。
Landing gear performance on the machine’s safety and comfort have a real impact. Taking the domestically produced aircraft turning system of a certain type as the research object, the nose landing gear turning system is simulated and analyzed through the simulation method of Virtual.lab and Imagine.lab, and the sensitivity of the nose gear is used to determine the landing gear forward inclination, , The stability distance and the vertical stiffness of the tire on the maximum static moment of landing gear moments. The analysis results show that: the landing gear front tilt angle of the maximum static moment of maximum impact.
