Modeling of segmental excavator working tool for soil compaction

Soil Compaction

Numerical simulation of dynamic soil compaction with vibratory compaction equipment

Roller drums make use of various shapes and their dynamic compaction effect is achieved by different kinds of dynamic excitation systems. The bearing capacity of layered soil constructions can be measured during the soil compaction process. The finite element method has been applied for dynamic analyses using elastic models. For the realistic simulation of the dynamic compaction process it is n...

Cutting and Impedance Model of Soil- Excavator Interaction

The present work considers a double wedge soil cutting model, suitable to describe the soil-tool interaction in automated digging processes. This one or a similar model will be the base to reach a set of equations by which to fit online typical soil and tool parameters, instead to fit these parameters by time consuming autoregressive methods. The final aim is to reach a predictor of soil-tool i...

Soil Compaction: Effects and Amelioration

Soil compaction was identified as the cause of ‘growth stunting disease’ in sultana grapes and ‘red death’ in cotton at the Lower Orange River and Vaalharts irrigation schemes. In an experiment growth stunting disease was eradicated completely and yields of sultanas increased substantially by deep cultivation, which eliminated compacted soil layers. Ripping increased the quality of tobacco, and...

Soil Compaction and Soil Tillage – Studies in Agricultural Soil Mechanics

Keller, T. 2004. Soil Compaction and Soil Tillage Studies in Agricultural Soil Mechanics Doctoral dissertation. ISSN 1401-6249, ISBN 91-576-6769-1 This thesis deals with various aspects of soil compaction due to agricultural field traffic, the draught force requirement of tillage implements and soil structures produced by tillage. Several field experiments were carried out to study the mechanic...
