Identification of Vibration Transfer to Car-body from Road Roughness by Driving Car

The article presents results of the research on identification of vibration transfer to car-body from road roughness by driving car. It is the case study of multiple sources of vibration generate on vehicle and transfer to driver and passengers. During the research the passenger car was driven on special test track and vibrations in 3 octagonal axes of the floor panel were recorded at locations where the vibrations were transferred into the human organism. The analysis of time-frequency distribution of the vibration allows to separate the main components of the signal.
