Industrial Drivetrain Simulation: From Gear Layout to NVH Analysis

Predicting and reducing gear whine noise originating from the intermeshing gear is a real challenge for designers. Modeling gear transmissions is laborious and cumbersome: transmission system consists of various components such as gears, shafts and bearings. Capturing all relevant effects (misalignment, gear microgeometry, housing flexibility) adds additional complexity for multi-body analyst. Typically, it takes up to several days for model preparation and simulation of the nonlinear dynamics to obtain system-level loads.

This paper introduces recent innovation in gearbox engineering to compose and simulate transmissions, at any stage of the development, more accurately, and in approximately 1 hour.
