Runway Friction Coefficient Test & Analysis Method under Uneven Condition
In order to achieve accurate and stable runway friction coefficient testing result, the unevenness factor of runway should be considered. Since runway unevenness is very complex, the effect analysis of ordinary analysis means is difficult to be proved. But the finite element means can be used to analyze especially complex model. In reality the airport runway is multilayer three-dimensional structure that is consist of the earth foundation, the base layer and the upper layer, the loads upon runway are moving dynamic changeable loads. When the finite element model being constructed it is needed to consider the runway unevenness degree, joints and runway plate size and so on. Since the airplane loads are moving upon runway surface, it is required to design in parameterization language to apply the loads time and again. In the paper, dynamic three dimension finite element means is utilized to analyze the effect of runway unevenness to friction coefficient, and a preliminary calculating model example was established at last.
