摘要: In order to study tillage power optimization, a tillage-force measuring system has been built with transducers in the three-point hitch mechanism, and then calibrated tested field. The uniqueness of this is its ability measure three orthogonal components force despite using only sensors; was possible by three-dimensional analysis tractor linkage mechanism. A dynamic calculus program developed take into consideration changes hitch-mechanism geometry during operation. calibration results showed linear relation between applied measured forces. preliminary field tests proved stability results. can readily be studies minimize energy consumption.
