The analysis of indentation of rigid cylindrical wheels into frictional/cohesive soils is presented. Threeand two-dimensional numerical simulations were performed using the finite element code ABAQUS to assess the influence of soil strength parameters, dilatancy, and wheel geometry on the relationship between the indentation force and wheel sinkage. The effect of three-dimensionality in the ind...

Analysis of stress distributions under lightweight wheeled vehicles Report Title In recent years, the need for reliable modeling tools for lightweight robotic systems deployed on various terrains has spurred research efforts into development of vehicle terrain interaction (VTI) models. This paper presents an analysis of rigid wheels dry sand interaction and compares experimental results with pr...

This paper revisited some wheel–workpiece interaction problems in surface grinding including the profile of heat flux and the variation of the wheel’s elastic modulus. A method of using an optical microscope and a CCD camera was applied to capture the depth and width of the heated zone, the details of the temperature field and the stability of the heat flux. It was found that the heat flux in u...

It is known that many systems have the regular structure constructed from several kinds of basic modules. We focus on parameterized asynchronous circuits with a wheel structure, which consists of one kernel module and many identical symmetry modules,and aim at verifying such systems of arbitrary sizes. In this paper, we propose a fully automatic state enumeration procedure for wheel structured ...
