Artigo:

This PAPER has the proposal to study the physics and the propagation of the transmission gear rattle, starting with the engine irregular combustion and the fluctuation of the torque generate the torsional vibration that passes to the transmission and excite the internal components and appears the noise. With simulations we will understand the enablers that act to reduce this torsional vibration and decrease the noise level, measure the hardware and correlate with the simulation to define a robust design that reach the vehicle technical requirements and a good satisfaction to the customer.
