Noise emanating from tractors is a potential health risk for operators, especially during prolonged working hours. As regulations governing noise radiation are made stringent, a first time right simulations based approach is needed to refine various noise sources of tractors. In present case study, powertrain noise optimization of an open station tractor has been carried out. Various noise sources of engine like; structure, intake, exhaust, timing gears and blower fan have been studied. NVH testing has been conducted for noise source ranking and establishing correlation with baseline simulations. Optimization has been performed on engine and it’s aggregates for achieving overall noise reduction of 3 dB(A) at tractor operator ear level, using; multibody dynamics, CFD simulations, linear acoustics and Rayleigh integral approach.
