Evaluation of whole-body vibrations and seat performance, and characterization of the postures related to heavy vehicle operation - Phase III: Definition of the design requirements for mining vehicle seats based on biomechanical and vibration analyses Abstract Whole-body vibration exposure is known to cause various health problems, in particular low back pain and disc degeneration. Considering the complexity of the problem, it is difficult to establish the link between vibration exposure and health problems. Research must therefore continue in order to determine effective means of prevention. This project is the first sharing of resources of the IRSST, Queen’s University, the University of Western Ontario and Laurentian University, with the financial assistance of the Workplace Safety and Insurance Board of Ontario. The Ontario researchers will carry out the first two phases of this project and the IRSST’s researchers will conduct the third. Their objectives are to estimate the characteristics of the vibrations transmitted to the drivers of heavy mining vehicles, to characterize their sitting posture, and to simulate the vibration of vehicles in the laboratory to evaluate the design requirements of better adapted seats. On the basis of biomechanical and vibration analyses carried out by simulating a driver’s station, this extensive joint research will provide a definition of the design requirements of safer seats and a better understanding of the effect of postural factors on the transfer of vibrations to drivers.
