Abstract:Strong aerodynamic force is generated between the wheels and road surface while a vehicle is moving fast on the road. As a result, the road surface is stroked by instantaneous and repeated aerodynamic force. For porous asphalt pavement, the repeated air pressure acted on the pavement would cause changes of water vapour state within, leading to pavement damage. Based on the 3D viscous incompressible Reynolds-averaged Navier-stokes equations and turbulence model k-ε double equation model, the aerodynamic field between the vehicle and pavement was analyzed with numerical computing methods. The relationships between air pressures around the wheels and vehicle speed were studied. The variations of the air pressures at the front and back of the wheel were obtained. A vehicle-mounted aerodynamic field testing device was developed. Air pressures of the front and back of moving wheels were measured with the vehicle-mounted device. Testing results agreed with numerical calculation. It was indicated that the developed device could be used to investigate the aerodynamic field in vehicle-pavement system.

Transactions of the Chinese Society for Agriculture Machinery (CSAM), in charged of China Association for Science and Technology (CAST), sponsored by CSAM and Chinese Academy of Agricultural Mechanization Science(CAAMS), started publication in 1957. It is the earliest interdisciplinary journal in Chinese which combines agricultural and engineering. It always closely grasps the development direction of agriculture engineering disciplines and the published papers represent the highest academic level of agriculture engineering in China. Currently, nearly 8,000 papers have been already published. There are around 3,000 papers contributed to the journal each year, but only around 600 of them will be accepted. Transactions of CSAM focuses on a wide range of agricultural machinery, irrigation, electronics, robotics, agro-products engineering, biological energy, agricultural structures and environment and more. Subjects in Transactions of the CSAM have been embodied by many internationally well-known index systems, such as: EI Compendex, CA, CSA, etc.
