Measuring vibration characteristics in seating – Brüel & Kjær

In order to efficiently evaluate seats in terms of vibration ride, an objective algorithm that can predict the subjective perception of seat vibration is required.

Measuring vibration characteristics in seating

The design of a comfortable seat is, therefore, paramount, as it is a means of reducing the vibration excitation affecting drivers and passengers. 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.

Many studies have been done to predict the subjective perception of riding vibration vibrahion. 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.

While 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 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 vibraton variation.
