Learn about the Polytec’s laser Doppler vibrometry applied to the characterization of automotive tires. Tire noise contributes significantly to the interior and exterior acoustic quality of cars especially with the EV. Validated FE models are essential to predict not only the tire noise, but also its contribution to the interior noise. The webinar will explain how tire simulation models are validated using vibration data from experimental modal tests and operational tests on a rolling road. Learn why 3D data are essential to resolve the modes and under which conditions measurements on a rolling tire up to high speeds can be performed.
