飞机起飞着陆过程中,前起落架所受外载荷不断变化。结合受载情况以及相关收放参数,通过建立飞机前起落架收放动力学模型以及液压模型,仿真计算出撑杆作动筒一端关节轴承的径向载荷。
During the take-off and landing of the aircraft, the external load on the nose gear is constantly changing. According to the loading conditions and the related parameters, the radial load of the spherical plain bearing at one end of the strut was calculated by establishing the retractable dynamic model and the hydraulic model of the front landing gear.
