Abstract:

A numerical model of wet soil-paddlewheel interaction was developed and validated against the experiments. The use of numerical computational methods to simulation of the wet soil-paddlewheel interaction reduces the experimental, design and development costs. In this study, SolidWorks software was used to design the paddlewheel and Abacus software was used for analysis. Coupled Eulerian-Lagrangian (CEL) method was applied for the analyses in which the soil and paddlewheel were introduced by Eulerian and Lagrangian formulation, respectively. Soil was modelled as an elastic- perfectly plastic material with Drucker-Prager yield function. The results showed that the wheel sinkage and slip increased by increasing drawbar pull. The stress inside the soil was shown to be increased due to the drawbar pull. Satisfactory agreement was found between the finite element model and experiments for slip; sinkage as well as rolling resistance. The finite element method was shown to be a confident method for wet soil-paddlewheel interaction and can be applied for effective parameter optimization. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .
