Abstract

The invention belongs to the field of impact dynamics, and particularly relates to a ground test device for simulating the landing impact process of a shipboard aircraft landing gear, and the device comprises a hanging basket which is vertically and slidingly arranged among a plurality of experiment table stand columns; a lifting mechanism, the bottom end of which being movably connected to the top end of the hanging basket; an aircraft landing gear which is arranged at the bottom end of the hanging basket; a tackle table track which is horizontally laid on the ground; a tackle table which isslidably arranged on the tackle table rail, and a top plate of the tackle table serving as a tackle force measuring platform; a tackle table propelling device which is used for providing thrust for the tackle table; a release control system which is used for controlling the lifting mechanism and the tackle table propelling device; and a data acquisition system which is used for data acquisition. The ground test device for simulating the landing impact process of the shipboard aircraft landing gear can meet the landing impact test requirements of the shipboard aircraft landing gear, ensures theconsistency of the ground working condition and the actual engineering working condition, can realize simulation tests of arresting, obstacle crossing and the like of the shipboard aircraft on the ground, and has a wide application prospect.

Description

technical field [0001] The application belongs to the field of impact dynamics, and in particular relates to a ground test device for simulating the impact process of landing gear of a carrier aircraft. Background technique [0002] For some aircraft, such as carrier-based aircraft, it is necessary to carry out simulation tests of carrier-based aircraft landing, short-distance rollover, overcoming obstacles and obstructions before the test flight to check whether the strength and stiffness of the landing gear during the landing process meet the design requirements. [0003] At present, for the aircraft drop test, a bench-type aircraft landing gear drop test device is often used. Generally, the wheel belt rotation device is used to drive the tires of the landing gear to rotate, which is equivalent to simulate the contact between the tires and the ship during the real touch-down / grounding process of the landing gear. Mutual motion between body / ground. However, during the ac...
