Vibrations on Board of Different Categories of Vehicles: A Method for Analyzing the Influence of Speed Bumps on Comfort

The findings of a study done on five distinct types of automobiles in a specified test site are presented in this paper. The goal was to see how the effect of the test site discontinuity influences variations in comfort as a function of speed and the five distinct classes of road vehicles. Data from vibrations in the three reference axes, detected by a vibration dosimeter (VIB-008), and geolocation data (latitude, longitude, and speed) identified by the GPS inside a smartphone were combined to obtain measurements. This approach has proved used in postprocessing to eliminate any measurement irregularities caused by the operator, thanks to the synchronisation of the dosimeter and GPS location. Following the survey campaign, it was discovered that a formula may be used to calculate a Comfort Index (CI) based on velocity and five different vehicle classes. There were also some reference thresholds and six vibrational comfort classes defined. The presence of speed bumps in the test site reviewed appears to be unsettling even at speeds much below those authorised by the Highway Code, according to this study.
