Mechanical Response Analysis of Asphalt Concrete Pavement Considering Braking Force of Aircraft
摘要
Abstract
Some significant impact produced in asphalt concrete pavement by braking force when aircraft landing. Three-dimensional finite element model for semi-rigid pavement and flexible pavement structure was created with ABAQUS software. Finite element model was adopted to analyze the mechanical response of the civil aircraft and new generation large aircraft with a consideration of the braking force. Meanwhile, an analysis was made of the influence of different braking force, different subgrade modulus and different interface condition between surface and base for B777-300ER and A380-800. The results show that the maximum tensile stress of surface appears at the top ofpavement by considering the braking force. The tensile stress in the surface increases significant when the braking force exceeds 0. 5 times of the single wheel load. The interface condition between surface and base affects the semi-rigid pavement more. When the contact coefficient between surface and base exceeds 0.5, influence for the maximum shear stress in the surface and the tensile stress at the bottom of surface is not significant.关键词
