Mr. Brian Grieser can provide the following services related to human vibration and biomechanics analysis:

  • Computer data acquisition and analysis of human vibration, acceleration/shock and force exertion data
  • Whole-body and hand-arm vibration assessments
  • Ergonomics / biomechanical analyses
  • Litigation technical support / expert witness

Summary of Mr. Grieser's experience / qualifications:

  • Projects involving the testing and analysis of human vibration (both whole-body vibration and hand-arm vibration), human exposure to acceleration/shock and human force exertion. Some applications include the following:
    • Vehicle seating
    • Locomotive engines and railroad track maintenance equipment
    • Off-road equipment
    • Heavy trucks
    • Car carrier / auto transport / auto hauler trucks
    • Lift trucks / fork trucks / fork lifts
