Abstract

The dynamic response of soil to farm implements is a main factor in determining their performance. The interaction between tillage tools and soil is of a primary interest to the design and use of these tools for soil manipulation. A computer simulation is conducted by developing a program using C ++ programming language to study effect of tool depth and width on angle of soil failure plane, soil cutting coefficients, soil resistance force and Power requirements in three-dimensional soil cutting. The results demonstrated that at 0.2 m tine depth the highest values of angle of soil failure plane, frictional coefficient, overburden coefficient, soil cohesion coefficient and soil adhesion coefficient were 52.6°, 19.8, 49.54, 16.47 and 1.38 respectively and they were recorded by 0.04 m tine width while the lowest values in same sequence were 51.6°, 10.64, 22.05, 7.26 and 1.30 and they were recorded by 0.1 m width. The lowest values of soil resistance force and power were 1.77 kN and 1.03 kW and they were shown by 0.04 m width while the highest values were 2.07 kN and 2.26 kW and they were demonstrated by 0.1 m width of tine. At 0.3 m tine depth the highest values of angle of soil failure plane, frictional coefficient, overburden coefficient, soil cohesion coefficient and soil adhesion coefficient were 52.7°, 27.42, 72.54, 24.11 and 1.39 respectively and they were recorded by 0.04 m tine width while the lowest values in same sequence were 52.3°, 13.70, 31.23, 10.35 and 1.35 and they were recorded by 0.1 m width. The lowest values of soil resistance force and power were 4.27 kN and 4.66 kW and they were shown by 0.04 m width while the highest values were 4.86 kN and 5.29 kW and they were demonstrated by 0.1 m width of tine. At 0.4 m tine depth the highest values of angle of soil failure plane, frictional coefficient, overburden coefficient, soil cohesion coefficient and soil adhesion coefficient were 52.8°, 35.04, 95.27, 31.73 and 1.39 respectively and they were recorded by 0.04 m tine width while the lowest values in same sequence were 52.5°, 16.75, 40.39, 13.40 and 1.37 and they were recorded by 0.1 m width. The lowest values of soil resistance force and power were 8.19 kN and 8.93 kW and they were shown by 0.04 m width while the highest values were 9.13 kN and 9.95 kW and they were demonstrated by 0.1 m width of tine. It was concluded that Angle of soil failure plane and soil cutting coefficients decreased as tine working depth and width increased. Soil resistance force and power increased as angle of soil failure plane and soil cutting coefficients decreased as tine working depth and width increased.
