Abstract

The transmission of vibration to the body will influence comfort, performance and the long-term health of the user. Vibration comfort assessment is a crucial chain of concurrent engineering. It's an imperative task for automotive manufacturers that firstly, evaluate the vibration comfort of their products then conduct the appropriate modifications. In this study, in order to evaluate vibration characteristics of a passenger car, vibration signals were measured while driving with different speeds over four road surfaces. Vibration dose values (VDVs), power spectral densities (PSDs) and kurtosis of the compartment recorded signals were evaluated to assess transmitted vibrations to the passengers. Results indicated that energy concentration was at frequencies lower than 30 Hz. Such low frequency excitations were well attenuated by seat suspension in vertical direction but amplified (up to 5 times in harsh condition) by backrest in fore-aft trend. On a suburban road, signals were amplified beyond 30 Hz but amplitudes were still very low. It seems that backrest assembly still can be improved to become a better isolator. Kurtosis and VDV had correlation with IRI and may be used as two objective metrics together with jury evaluation to derive vehicle vibration comfort index in the future.
