双层多孔隙沥青路面吸音降噪有限元分析
Finite element analysis for noise-reducing of double-layer porous asphalt pavement
摘要
Abstract
For single-layer porous asphalt pavement easy blocking, double-layer porous asphalt pavement structure was brought out. The numerical simulation for acoustic absorption properties of porous asphalt pavement structure was made with application of finite element method and acoustic-solid coupling model by large-scale commercial software ABAQUS. The noise-reducing feature was analyzed for the double-layer porous asphalt pave- ment in porosity and thickness combinations and then structural parameters suitable for double-layer porous pave- ment was proposed. The result indicated that double-layer porous asphalt pavement has better sound absorption for upper and lower-layer porosity of 10% , 25% , the upper and lower-layer thickness of 2 cm, 4 cm. The con- clusion can provide a theoretical basis for the application of double-layer porous asphalt pavement.关键词
