Pravin Patil is the Global Drivetrain NVH Simulation Lead at John Deere, with 15+ years of expertise in drivetrain NVH, durability, and testing. He specializes in dynamic simulations to mitigate gear noise and has served on the AGMA Sound & Vibration Committee. He holds a master’s from IIT Kharagpur.
In the realm of tractor gearbox applications, gear whine noise has long been a persistent challenge that significantly impacts the user experience and overall perceived performance of the vehicle. This paper delves into a comprehensive study that discusses the approach to tackling this issue through a combination of design optimizations, simulation techniques and physical validation processes.
