Research On The Clibration Device Of Airport Runway Surface Friction Tester

As rapid development of economy and significant increases of travel, business activities and foreign exchanges, the airline industry also develops at a relatively rapid speed.By 2005, there are more than 150 national airports to civilian, but the traffic of the plane running out of the runway often occurs, most of which is due to the low friction coefficient of the airport runway.For security, friction coefficient testing of airport runway will become more and more important. Friction coefficient car is an equipment vehicle which devoted to testing friction coefficient of airport runway . Because such vehicles can not be produced by our country or unable to reach the corresponding performance indicators, we must spend more than 200 million yuan on foreign imports. But from abroad in the use of the airport runway friction coefficient test purchase of vehicles demarcation device error is found, it is impossible to guarantee the next instrument.But the airport runway friction coefficient tester buying from abroad is found that the error of the calibration equipment is too large and it is impossible to guarantee the next instrument. This topic is a special study funded by the CAAC which is based on the automatic calibration system research of friction coefficient tester on airport runway.The main contents include the following researchs:(1)The research of automatic testing mechanism of friction coefficient tester on airport runway(2) The research of controlling system of friction coefficient tester on airport runway(3) Advancing better method of friction coefficient tester on airport runway according to the fact of our country.(4) Investigating and producing high-powered calibration equipment of friction coefficient tester on airport runwayThis text provides a calibration equipment which is suitable for friction coefficient tester on airport runway using in our country now, find relative merits and better method of friction coefficient tester on airport runway and point out the development direction of friction coefficient tester on airport runway.
