Bruel & Kjaer Sound & Vibration Measurement A/S | ACI EUROPE
Many studies have been done to predict the subjective perception of riding vibration comfort. A comfortable and mesuring ride is an important factor for drivers and passengers alike when they decide which vehicle to buy. Vibration Roughness explained our subjective data better than the traditional metrics using only vibration energy, and the predicted results were less affected by the sensor locations and directions.
Measuring vibration characteristics in seating
The relevant studies and standards are based only on the estimation of vibration energy with a frequency weighting function applied and often do not take into account the amount of temporal variation.
Measuring vibration characteristics in seating A long commute is often stressful and tiring, so comfortable seating becomes increasingly important for drivers as well as passengers. Vibration induced by powertrain, ancillaries and road can dramatically affect how passengers judge the quality of the ride.
A long commute is often stressful and tiring, so comfortable seating becomes increasingly important for drivers as well as passengers. Bruep the on-road subjective assessment provides more realistic ratings of seat vibration quality, it is not cost-effective and does not provide the subjects with the possibility of back-to-back comparisons, that is, comparing two or more different seats, one after another, within the same experimental session.

The design of a comfortable seat is, therefore, paramount, as it is a means of reducing the vibration excitation affecting drivers and passengers. Get Waves directly in your inbox. ISO is the most often used standard for this purpose.
