Comparative Analyses of the 4WD Tractor Performance with Two Different Mouldboard Plow Bottoms by Using FEM

Abstract

A theoretical work was performed to model and design the bottom of a cylindroidal type mouldboard plow. The aim of the work was to compare and evaluate the performance of the two different types of mouldboard plow designed and type 113 in two soil depths 15-20 and 20-25 cm and three forward speeds 4.4, 6, 9 km/h . Some design indicators involved in the study; draft force, von mises stress and bending moment which were analyzed with using a finite element methods FEM . Some soil indicators involved; plowing appearance, the degree of tilth, the evens of the plowing surface and the angle of inclination. The data were then analyzed statistically with using randomized complete block design for all indicators and characteristics. Designed mouldboard plow was found to be significantly superlative over the 113 mouldboard plow with all design indicators since the draft force, von mises stress and bending moment were less. The results showed draft force, von mises stress and bending moment increased by increasing forward speed with a constant depth, and also showed the draft force, von mises stress and bending moment increased by increasing the depth with a constant speed for both plows in the theoretical and experimental results. Best performance results were obtained in 15-20 cm soil depth with 9 km/h forward speed
