Abstract

In this research, the performance of a double-tilled excavator plough was evaluated compared to a single-tilled excavator plough in clayey soil: a modeling and simulation study. An integrated mathematical model was developed using MATLAB-2014b and the stress distribution was simulated using the Mohr-Coulomb failure criterion. Then, analyzed the pull, shear and compression forces for both designs and studied the effect of speed (5-8 km/h) on energy consumption.

The results showed that the pulling force decreased for the traditional toggle from (85.3 kN) to (72.9 kN) for the proposed double toggle, i.e. saving (14.5%), the energy consumption of the pulling machine decreased from (90 kw) to (77 kw), i.e. saving (14%), and the maximum stress decreased from (284.2 kpa) to (198.9 kpa), i.e. saving (30%). There was a noticeable improvement in regularity and balance resulting from the stress distribution.

The research proves the superiority of the dual design in performance and efficiency, making it a better choice for clay soils from a technical, economic and environmental standpoint.
