the single wheel tester is an experimental device used to measure wheel forces when studying the relation of soil and wheel in a soil bin or in the field. in the model under development, a special frame holding the test wheel is connected to a loading carriage by two pairs of vertical rails and four rollers to provide a floating connection. by applying a driving torque to the test wheel shaft, ...

the tire-mechanics models have been developed for the study of wheel movement on the road or soil surface while these models are unlikely to describe the motion of wheels on uneven surfaces. due to dynamical complexity of this phenomena and the importance of this subject for farm conditions and the wheel carrier devices, the present research aimed to investigate the effects of several parameter...

The knowledge of the available power provided by the driving wheel of agricultural tractors is required to gain a correct insight into the energy management of agricultural tractors. The design of the tractors is pivotal on the maximization of the traction efficiency and simultaneous minimization of energy dissipation. This paper spearheads the synthesis of the power provided by the agricultura...

Turnouts are the weak spot in high-speed rail systems, and it is simple for phenomenon of wheel–rail force carbody lateral acceleration over-limit to arise when train passes through, which affects service life running stability train. In this paper, turnout with selected analysis, profiles wheel monitored. Then, vehicle–turnout coupled multi-body dynamics model simulated. Additionally, portable...

Various methodologies of artificial intelligence have been recently used for estimating performance parameters of soil working machines and off-road vehicles. Due to nonlinear and stochastic features of soil–wheel interactions, application of knowledge-based Mamdani max–min fuzzy expert system for estimation of contact area and contact pressure is described in this paper. Fuzzy logic model was ...

The wheel pair is a key component of the subway. Routes subway conditions are more complex, while frequent starting and braking likely to cause damage. To improve sliding tribological properties wheels, this article focused on laser-cladding technology repair wheel. Ni-based Fe-based alloy coatings were prepared. microstructure was studied by SEM, EDS, XRD, 3D optical morphology. mechanical coa...
