Abstract
Earlier cultivation and tillage tools were designed on the basis of practical experience; testing and records of fundamental theoretical analysis of these tools is largely lacking. Today, the release of new equipment is always preceded by several years of laboratory tests and field experiments. By modelling the interaction between the soil and tillage tools, the time and costs of the development process can be significantly decreased. Thanks to the recent rapid advancement of high performance computers and numerical methods, it is possible to complete these model calculations more effectively now. With the help of a combined FEM/SPH simulation – in this case utilizing two different driving speeds of a tractor – we determined the magnitude of horizontal force acting upon the rotating tool as a function of time. Using the functions fitted to the simulation results, the authors have calculated the average and the maximum values of the horizontal force. Moreover, normal stress distribution in the soil has also been determined.
