The invention discloses a frame type undercarriage with an adjustable structure for a test. The frame type undercarriage aims at solving the problem that an existing fixed undercarriage is insufficient in flexibility under variable test conditions. The undercarriage comprises a bearing module, a frame module and a buffer module. The bearing module comprises a plurality of bearing units, and each bearing unit comprises an axle, two wheels, a bearing, two axle sleeves and two limiting hoops. The frame module is used for adjusting the main, starting and retreating distance and the tire distance. The buffer module comprises an oil gas buffer, an anti-torsion arm and a buffer base. Through the adjustable frame structure, different test requirements are met, the test cost is reduced, the research and development period is shortened, the performance and safety of the aircraft in diversified environments are improved, and the aircraft has remarkable practical value and wide application prospects.

    本发明公开了一种试验用可调节构型车架式起落架,旨在解决现有固定式起落架在多变试验条件下的灵活性不足问题。该起落架包括承重模块、车架模块和缓冲模块。承重模块包含若干承重单元,承重单元包含轮轴、两个车轮、轴承、两个轴套和两个限位卡箍。车架模块用来调节主起后退距及轮胎间距。缓冲模块包括油气缓冲器、防扭臂和缓冲基座。本发明通过可调节的车架结构,适应不同试验需求,降低试验成本,缩短研发周期,提升飞行器在多样化环境下的性能表现和安全性,具有显著的实用价值和广阔的应用前景。
