Sensitivity analysis of tractor performance prediction model

Abstract

A sensitivity analysis was performed to identify tractor performance parameters that have the greatest effect on tractive efficiency. The sensitivity of the model resultsr elativet o the inputsw as detelrnineds irnultaneouslyW. ith the base values, rear wheel load had the highest relative sensitivity. Rearwheel slip had the lowest relative sensitivity, where the model result was near its peak. However, lower and higher rear wheel slip values resulted in highly sensitive rnodelw ith input paranletelsv aried+ 0.05 fi'ornt he basev alue.
