A path-tracking criterion for the so-called LHD (load-haul-dump) truck used in underground mining is proposed in this paper. It exploits the particular configuration of this vehicle, composed of two units connected by an actuated articulation. The task is to follow the path represented by the middle of the tunnel, maintaining the whole vehicle at a reduced distance from the path itself, to decr...

The main object was to perform simulations using a realistic model of a truck and trailer passing over a flexible bridge structure. The bridge structure was simplified to a flat surface modeled using shell finite elements. Tire normal, lateral and longitudinal forces were applied to the bridge. Three driving cases were considered: straight forward driving with and without braking and a lane cha...

Overall comparisons of crash rates based on mileage indicate that truck crash rates are lower than car crash rates, but that truck crashes are more severe. In 1978 the overall U.S. crash rate for cars was estimated at 8.2 accidents per million vehicle-miles of travel; for large trucks (including combinations) the rate was 4.7 per million vehicle-miles, and for combination trucks (e.g., tractor-...

In traffic data collection, sampling design should satisfy the requirements of identifying prominent pulses corresponding to vehicle axle passage. Insufficient measurement leads signal distortion and attenuation, reducing quality pulses. This study exploits value under-sampled by applying compressed sensing (CS) methods recover components that are critical for detection. Two CS investigated in ...

Abstract The article examines issues related to the design of road tax as an instrument supporting operation trucks that are more environment-friendly transport infrastructure. Introduction presents analyses taxation in European Union Member States, whose aim was identify features eco-friendly with regard principal part contribution is formulation a regression model rates, which subjected stati...

Initially, the first aim of the present study is to model 3-axle rigid truck by developing a code in Matlab. Secondly, each equation should be drived by acquisition of Lagrange approach. After deriving equations successfully, validation is performed by some result which was mentioned in Bohao Li's master thesis. Although the present approach is totally different from the approach that Boahao Li...

In this paper, we developed truck fuel consumption models for the particular assistance of professionals in charge road project valuation terms predicting used by trucks, which is an important topic on vehicle operating costs to be considered benefit–cost analysis projects. On other hand, has a direct impact emissions atmosphere, and thus future research can conducted regarding estimations abou...
