摘要
分析了前起落架的摆振试验,在LMS Virtual. Lab仿真环境中对某型飞机前起落架的实验室摆振试验进行动力学建模与仿真分析。参考前起落架真实滑跑时的参数得到前起落架的验证工况,研究了该工况下前起落架摆角、地面侧向力、摆动角速度、防摆阻尼力矩的时间曲线。此外,分别绘制出不同立柱刚度以及间隙下的摆角时间曲线,分析其对摆振试验的影响。
This paper analyzes nose gear shimmy test. The dynamic modeling and simulation analysis of a certain type of aircraft landing gear is carried out in the LMS Virtual. Lab simulation environment. Referring to the parameters of nose gear when taxiing, verification conditions of nose gear is gained. And the swing angle of nose gear, lateral force, angular velocity, anti-swing damping torque time curve under verification condition are studied. In addition, the time curves of different column stiffness and the swing angle of the gap are plotted respectively, and the effect of nose gear shimmy test on shimmy testis analyzed.
