Research on the relationship between longitudinal road unevenness and ride comfort in vehicle


Project start:01.01.2016
Project end:31.12.2018
Programme:VEGA
Project number:2/0089/16
Institute position in the project:The only one project investigator
Project leader:Peter Múčka
The project is aimed experimentally determine the relation between ride comfort on the driver seat in a motor vehicle and measured longitudinal road unevenness. Parameters of the measurement will be vehicle type, vehicle speed, road type and level of longitudinal unevenness. The aim is more accurately classify road unevenness using the measured response of vibration acceleration. Group of unique in situ measurements will be faced with different road classifications often based on simulated vibration response. Possibility of different road unevenness indicators to reflect ride comfort will be estimated. Relation between the parameters of road elevation power spectral density (unevenness index and waviness) and ride comfort will be estimated, which has not yet been published. Results could provide a contribution to anincrease in ride comfort, ride safety and decision making on road maintenance.
