Embodiment Construction

[0028] Below in conjunction with embodiment and accompanying drawing, the present invention will be further described:

[0029] Connect the wheel landing gear system (10) to the bottom of the hanging basket (2) through the three-way force sensor (5), adjust the weight of the counterweight (4) to match the corresponding vertical load of the wheel, and use the EMAS material (11 ) is evenly laid on the platform (12) of the tackle platform, and the hanging basket is hoisted by the lifting mechanism (1) and placed on the top of the platform without material at the front end of the tackle platform, keeping the wheels in contact with the platform without heavy pressure, so that the wheels and the platform The synchronous belt rotates, the trolley propulsion system (13) is filled with corresponding pressure, and the trolley is launched along the trolley track (8) at a certain speed, and the wheel rolls the EMAS material to absorb the kinetic energy of the trolley, and passes through th...

Abstract

The invention belongs to a structural impact dynamics experimental technology, and particularly relates to an experiment apparatus and an experiment method for the dynamic energy absorption characteristic of an arresting system. EMAS is a safety facility for blocking the safety hazard caused by the running of the large aircraft out of the runway and is spread at the end of the airport runway, andthe predictable blocking resistance can be produced for the aircraft through the aircraft wheel rolling material, such that the aircraft can reduce the speed and stay in the safe area under the premise of the safety so as to ensure the structure of the aircraft and the safety of the occupants. The invention provides an experiment test method for performing dynamic energy absorption characteristicsof EMAS, and designs a special experiment table frame for researching the influence of the type of an aircraft landing gear wheel, the vertical loading state of the wheel, the wheel rotation speed and other parameters on the arresting load of EMAS. According to the present invention, the support can be provided for the research and development of the emergency arresting system at the ends of civil aviation and military airport runways, the real aircraft verification experiment of the rushing of the real aircraft into the EMAS material can be partially replaced, and the apparatus and the method have advantages of economy, high efficiency, strong operability, wider application prospect and the like.

Description

technical field [0001] The invention belongs to the technical field of structural impact dynamic mechanics experiments, and relates to an experimental device and an experimental method for the dynamic energy absorption characteristics of an arresting system, in particular to an experimental device and an experimental method for the dynamic energy absorption characteristics of an engineering material arresting system (Engineered Material Arresting System, referred to as EMAS). method. Background technique [0002] Aircraft running out of the runway during takeoff and landing is one of the main threats to aviation safety. The energy-absorbing engineered material arresting system (EMAS) laid in the safety zone at the end of the airport runway is an effective way to stop the safety hazard caused by the aircraft running out of the runway. facility. EMAS uses the collapse of the arresting material under the rolling of the aircraft wheels to absorb the kinetic energy of the aircra...
