| 摘 要： | 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。

| Abstract: | The performance of landing gear is of direct influence on safety and comfortable of aircraft. A steering system of certain domestic plane is taken as study object. The steering system is analyzed and simulated by using the Virtual. lab and Imagine. lab software co-simulation methods. The primary factor which affects maximum static steering torque of the landing gear amongst the factors such as forward angle, wheel space, castor trail, tire vertical stiffness is determined. Analysis result shows forward angle affects maximum static steering torque of the nose gear primarily. |
