Shipboard aircraft undercarriage test device and test method

Abstract

The invention relates to the technical field of shipboard aircraft undercarriages, and particularly relates to a shipboard aircraft undercarriage test device and a test method. The shipboard aircraft undercarriage test device comprises a sliding locating module, an undercarriage module, an acceleration module, a deck module and a dynamometer module, and is characterized in that the sliding locating module comprises a horizontal sliding rail and a positioning rope, the undercarriage module comprises a counterweight, an undercarriage elastic support and an undercarriage model, the acceleration module comprises an oblique plate acceleration device, a spring acceleration device and an oblique plate guide rail, the deck assembly comprises a stiffened plate rack and an elastic support, and the dynamometer module comprises a dynamometer. According to the test device and the test method provided by the invention, the elasticity of a deck, influences of water and swaying of a chip involved in the drop process of the chipboard aircraft undercarriage are simulated, and drop tests with a horizontal speed and a vertical speed of the undercarriage can be simulated, so that a load stroke curve of the undercarriage is acquired, and the curve is regarded as a general reference curve of the undercarriage in various conditions.

Description

technical field [0001] The invention relates to the technical field of landing gear of a carrier-based aircraft, in particular to a test device and a test method for a landing gear of a carrier-based aircraft. Background technique [0002] All spacecraft manufactured by humans have a process of lifting off the ground. Except for disposable space rockets and other aircraft that do not need to be recovered, most aircraft have a recovery and landing process. The landing gear is used as the landing gear of the aircraft. It is an important load-bearing component, which is used to reduce the impact of the aircraft's take-off and landing, airport taxiing and ground movement. The aircraft mainly relies on the landing gear to dissipate the impact from the ground during take-off, landing touchdown and ground taxiing. Thereby reducing the load on the fuselage and protecting the aircraft from landing safely. The landing gear of the aircraft will bear a large impact load during the land...
