Modelling Tractive Performance for Drive Wheel

A model was developed by regression analysis to predict the tractive performance of 7.00-18 radial ply tire for agricultural tractors. Different parameters that affect the cone index of soil and wheel slip were considered for the analysis. To obtain experiments values belonging to tractive performance of tire, a study was conducted in the soil bin by using a single wheel agricultural tire test machine. Performance of this model was compared with model developed by Wismer and Luth (1974) to predicted tractive performance. Mathematical and statistical methods were used to fitting and analysing of models. Results showed that M₁ model outputs were closer to experimental values than M₂ model outputs for prediction of traction performance
