Identify the peaks of harmonic response during operation of nonlinear rotor dynamics
In this blog, we shown the possibility of computing the harmonic response, Campbell diagrams, the critical speeds at which resonance occurs and the stability of a system that contains geometric nonlinearities coming from their bearings.
Beyond engine noise reduction – the future of powertrain NVH
For many years, NVH engineers have focused on solely one objective: engine noise reduction and cancellation techniques. What comes next? How would you define the role of the powertrain NVH engineer in this era? And what is the next challenge that he/she will face?
