An aircraft traction test platform based on hydraulic power comprises a track system, a hydraulic power system, a mobile platform and a lifting frame. The track system is positioned below the whole device; the hydraulic cylinder power system comprises two parts, one part is a traction hydraulic system arranged in front of the moving platform, and the other part is a lifting hydraulic system arranged on the two sides of the lifting frame; a wheel holding mechanism formed by the moving platform and the lifting frame is located above the rail system. The detachable integrated frame of the lifting frame is taken down by unscrewing the nuts, the airplane wheel is jacked to the front supporting table, then the detachable integrated frame is installed back, the nuts are screwed, and the airplane wheel can be held tightly; the lifting frame is jacked up through the lifting hydraulic systems on the two sides, and airplane wheels can be lifted up. The traction hydraulic system pulls the mobile platform to walk, so that the airplane can be dragged to walk. The method can be used for start-stop dynamics analysis and vibration characteristic research of the airplane in a traction state.
一种基于液压动力的飞机牵引试验平台,包括轨道系统、液压动力系统、移动平台与举升框架。所述轨道系统位于整个装置的下方;所述液压缸动力系统包括两部分,一部分为牵引液压系统置于移动平台前方,另一部分为举升液压系统置于举升框架两侧;所述移动平台和举升框架共同构成的抱轮机构位于轨道系统上方。本发明通过旋开螺母将举升框架的可拆卸式一体框架取下,将飞机机轮顶至前托台,然后再将可拆卸式一体框架装回并旋紧螺母,可实现对飞机机轮的抱紧;通过两侧举升液压系统顶起举升框架,可实现飞机机轮抬起;通过牵引液压系统牵引移动平台行走,可实现牵引飞机行走。本发明专利可用于飞机在牵引状态下的启停动力学分析以及振动特性研究。
