Evaluation of whole-body vibration exposure of operators of soil compactors
The IRSST published an evaluation of whole-body vibration (WBV) exposure of operators of soil compactors. Single-drum vibratory compactors are widely used for compaction of soils and road building.
This study investigates vibration properties and operator exposure to WBV of single-drum vibratory soil compactors through measurements, and presents spectral classes of vibration that could be applied for identifying desired interventions. Two test series were undertaken to characterize the mechanical vibration properties of the vehicles and vibration exposure of the operators. The first test series was performed on a test track under controlled conditions, namely, the speed, the amplitude of vibration due to the rotating mass integrated within the drum and the soil properties. The objective was to determine the vibration behaviours of the vehicles in terms of dominant ride frequencies and probable vibration modes. The second test series was undertaken at two different worksites in Québec in order to quantify and assess the WBV exposure under typical working conditions.
