Automatic vehicle classification (AVC) systems provide information about classes of vehicle that can be used for many purposes. This paper describes a axle count and axle spacing using wireless accelerometers sensors and magnetometers sensors. The vehicle axles are detected by accelerometer sensors, and the vehicles arrivals, departures and speed are estimated by magnetometers. The prototype sy...

This paper focuses on acoustic road traffic monitoring and looks, more specifically, into the problem of joint speed and wheelbase length estimation of two-axle vehicles as they pass by. It is known that both front and rear axle trajectories may be observed using a cross-correlation based processing in conjunction with a well designed two-element microphone array placed on the roadside. This is...

Abstract The axle load acts on the box unit and has shock-pulse nature when car is moving, that can lead to a mutual change in surface positions of roller ends with edges bearing races. ways are proposed optimize internal geometry radial end contact elements unit. It eliminate occurrence possible conditions movement rollers into thrust locking by increasing minimum limit clearance box.

Traffic volume and vehicle load are one of the causes road damage. The research was conducted on Road Governor Soebardjo. objective to determine effect traffic standard loads method used is regression analysis correlation. This obtains relationship between (equivalent single axle load/ESA) damage with r P values. study results show a weight yields equation y = 6E-07x2 + 0.0038x 0.3849 robust co...

The performance of agricultural tires varies with the characteristics both terrain and tractors on which they are mounted, differently affect rolling resistance, traction capacity, slip. To reduce variability test conditions, CREA developed an original mobile (MTB) bench consists a dynamometric single axle trailer pulled by tractor can be used in tests (driving wheels) resistance (driven wheels...

A three-dimensional vehicle-axle box bearing coupling model is established. The can calculate the contact force in three directions and obtain dynamic response of axle under real vehicle running environment. load distribution on double row tapered roller analyzed, co-simulation conducted by comprehensively considering transmission between bearing. Taking into account great impact defects bearin...
