Aircraft wheel-runway friction coefficient measuring vehicle and use method

Abstract

The invention belongs to the field of airport aviation ground special equipment, and particularly relates to an aircraft wheel-runway friction coefficient measuring vehicle and a use method. The measuring vehicle specifically comprises a mounting platform, a gravity center adjusting device for changing the gravity center position of the measuring vehicle, a steering device for adjusting the rotation angle of a measured wheel, a matched locking device, and a front wheel driving device for driving the measuring vehicle to move. Based on an integral structure, the vertical load on the measured wheel is automatically changed through the control system, so that multiple groups of experimental data are obtained, friction coefficient measurement is more accurate, longitudinal rolling/sliding and transverse sliding of the airplane wheel can be measured, longitudinal, and transverse and longitudinal and transverse coupling friction coefficients can be achieved by adjusting the rotating angle of the measured wheel; measurement functions are more comprehensive, and the use method is simpler.

Description

technical field [0001] The invention belongs to the field of airport aviation ground special equipment, and in particular relates to an aircraft wheel-runway friction coefficient measuring vehicle and a use method thereof. Background technique [0002] With the rapid development of my country's air transport industry, the number of aircraft take-offs and landings has increased significantly. In order to ensure flight safety and maintain the interests of airlines and passengers, especially in rainy and snowy weather, the friction coefficient of the runway directly affects the Whether the second flight can be successfully completed. Therefore, in order to obtain the accurate value of the friction coefficient of the airport runway surface in time in rainy and snowy weather and in the daily maintenance of the airport runway, a device that can quickly, stably and accurately reflect the friction coefficient between the aircraft wheel and the road surface and method of use are of g...

Problems solved by technology

[0003] At present, there are mainly two types of aircraft wheel-runway friction coefficient measuring devices, one is drag type, you can refer to the SARSYS-ASFT friction coefficient test vehicle, and the drag type friction coefficient vehicle requires special vehicles to be pulled in front, which is not convenient enough At the same time, it will increase the operating cost of the airport; the other is the integral type, such as the several airport runway friction coefficient vehicles produced by the Swedish ASFT company currently used in domestic airports, the price of which is more than 1.5 million yuan, and the operation of the test vehicle requires a full-time maintenance Personnel require a high level of operation; with the increase of flights, the scheduling of test vehicles is tense. If the friction coefficient of the airport runway cannot be obtained in time, there will be a huge potential safety hazard
