Prediction of Draft Force for Ard plows Using Dimensional Analysis in Silt Loam Soil

Abstract

The aim of this research is to determine the draft force of Ard plough in silt loam soil. Field and laboratories test were taken to measure the actual draft force and utilize it as input for draft prediction. PI-Buckingham's pi theorem using dimensional analysis used to develop a mathematical model. IBM SPSS statistics software was applied to validate and verify the developed model. The relationship between the measured and predicted values of the draft force evaluated R² is 0.91. The predicted draft force value of skewness and kurtosis is in the range of accepted values. The performance of the predicted draft force was checked using RRMSE and CRM. Investigation findings demonstrate that the derived mathematical equation was successful and viable for predicting the draft force of an ard plow in silt loam soil.
