NVH

Postdoc in multi-scale modelling of composites vibration response @ Ghent University (Belgium)

Submitted by wvpaepeg on

Nowadays, there is an increasing interest to use composite materials in automotive applications, in particular the use of fibre-reinforced plastics (carbon or glass fibres in a polymer matrix) is widely considered. The use of lighter materials, and hence a reduced fuel consumption, can be one of the possible solutions for reduced CO2 emissions. As the automotive industry is mainly familiar with metals and plastics, a lot of research is being spent on the mechanical response of composites under fatigue and impact loading, and on developing new design methodologies for these "new" materials.

What's that Car Noise? New SIMULIA Tech Brief Available: NVH Analysis with Rolling Tires

Submitted by matt.ladzinski on

The sources of noise in a vehicle are many, including the engine, driveline, tire contact patch and road surface, brakes, and wind to name a few.  A Noise, Vibration, and Harshness (NVH) engineer is tasked with predicting these noises early in the design phase to make the necessary adjustments to ensure a harmonic ride, so to speak. The latest SIMULIA Tech Brief illustrates the effects that rolling tires have in contributing to NVH.
