Abstract


The article aims to present the measurements of whole-body vibrations (WBV) and the calculation of seat-to-head transmissibility (STHT) for an agricultural tractor driver. Measurements were taken on a diesel tractor model TD80D and an electric tractor model TE-0. The measurements were performed under real operating conditions on a rough road at a speed of 5 km/h. Vibration levels were measured using five tri-axial accelerometers from Biometrics Ltd and NexGen Ergonomics. Data were collected simultaneously in real-time from all sensors using three Data Log units from the Biometrics Ltd data acquisition and processing system. The results obtained using Vats software after the comparative analysis are in accordance with the standard that describes the evaluation of human exposure to whole-body vibrations, ISO 2631-1, in the frequency range of 0-80 Hz.
