Skidding operations induce changes in soil physical properties, which have the potential to impact soil sustainability and forest productivity. Our objective was to investigate the effects of traffic frequency, trail slope, and soil moisture content on soil compaction, total porosity and rut depth. Treatments included a combination of three different traffic intensities (3, 7, and 14 passes), t...

The friction force for aircraft landing is mainly provided by the texture of runway surfaces. mechanism underlying generation energy dissipation tire rubber materials during random excitation induced asperities. However, surface deteriorated cyclic loading and environmental effects service life a runway, leading to loss braking extension distance. Additionally, when an lands on wet at high velo...

ABSTRACT The safety of highways with a high ratio bridges and tunnels is related to multiple factors, for example, the skid resistance pavement surface. In this study, distribution accidents under different conditions was calculated investigate relationship between road incidence traffic based on accident data Yuxiang highway. Statistical results show that weather alignment may affect accidents...

It is important to minimize the energy consumption of autonomous ground vehicles (AGVs) deployed in real world missions. One of the ways that this can be accomplished is to choose the vehicle’s motion to minimize the mechanical and electrical energy usage required by the vehicle’s motion. This paper considers energy efficient motion planning for skid-steered AGVs, an important and large class o...

In order to solve the equilibrium problem related compaction degree, structural integrity of skid resistance, and resistance asphalt wearing layer on a concrete bridge deck, influence rolling mode performance was analyzed according curve characteristics, image processing technology, laser method from mechanism temperature control equipment. The results showed that degree times an SMA-13 course ...
