CAE [computer aided engineering] analysis of NVH of ICE & Electric vehicles

Moin Mujawar CAE analyst

The Course structure was very constructive. Milind Sir has extensive experience in NVH & Acoustics domain. The way he explained NVH and acoustics concepts made even complex topics easy to understand and apply. His practical insights and structured approach added great value to the learning experience. I truly found this course to be highly informative and beneficial, and I would strongly recommend

Initially, I wasn’t sure what to expect from this course, given I’ve already dealt with vibration issues on real programs. Coming from an automotive background, the sections on BSR, rough-road excitation, and hydro-mount tuning directly mirrored problems seen during vehicle launch phases. The link between FFT-based signal processing and order tracking finally closed a gap that had been mostly handled by trial-and-error on past projects. The aerospace examples around rotor dynamics and modal testing were also useful, especially when comparing high-speed rotating assemblies to driveline torsional vibration cases. Even the agriculture-related references, like vibration exposure on tractor powertrains and operator comfort, felt grounded and not academic. One challenge was keeping up with the depth of the FE eigenvalue methods combined with multi-body dynamics; that took a couple of replays to digest. A practical takeaway was a clearer workflow for vibration root-cause analysis, from measurement through transfer path analysis, instead of jumping straight to hardware fixes. Some concepts, like non-linear vibration behavior, pushed outside daily work, but they helped explain issues that never quite fit linear models. The content felt aligned with practical engineering demands.

This course turned out to be more technical than I anticipated. The depth around resonance management and damping modeling went beyond the usual textbook treatment, especially when finite element eigenvalue analysis was tied directly to experimental modal testing. That linkage mirrors how we actually validate models in automotive NVH work, not how it’s often idealized. One area that stood out was the treatment of driveline torsional vibrations and order tracking. In automotive and agricultural machinery, those low-order excitations are where most field complaints live, yet they’re often oversimplified. The discussion around edge cases—like speed-dependent mode coupling and mount nonlinearity—was refreshingly honest. On the aerospace side, the contrast between vibration dose values and fatigue-driven design practices highlighted how different industries prioritize risk. A real challenge was keeping the signal processing concepts straight once FFT, TPA, and rotor balancing were layered together. The examples helped, but it still required revisiting some fundamentals to avoid misinterpreting spectra in transient conditions. A practical takeaway was a clearer workflow for root-cause vibration investigations, from measurement strategy through system-level mitigation, rather than jumping straight to component fixes. That mindset aligns well with industry practice and avoids costly rework. It definitely strengthened my technical clarity.
