Inverted cup-type drop test bed cradle

The invention discloses an inverted cup-type cradle for use in a drop test of a landing chassis, which is an important component for use in the simulation of the normal weight of an aircraft and the loading of the landing chassis of a landing chassis drop test bed and for forming a drop system with the landing chassis drop test bed. The cradle comprises a box body, a cradle top plate and a guide device using the inverted cup-type cradle to do linear motion vertical to the ground, wherein the guide device is fixed on two opposite sides of the box body; and the lower surface of the cradle top plate is provided with a fixing device for mounting the landing chassis to form a inverted cup-type structure, and the inside of the inverted cup-type structure is provided with a rigidity adjusting device. Compared with the conventional cradle, the inverted cup-type cradle has the advantages of saving the space and height and construction cost of the drop test bed, along with adjustable multidirectional rigidity, short power transmission route, large rigidity, and capacity for simulating the normal weight of a miniature aircraft.
