Abstract

Previous studies have shown that exposure to whole-body vibration can interfere with comfort, activities, and health. In analogy to materials handling it is assumed that the elevated spinal forces are a crucial component in the pathogenesis of the health impairment. To estimate the forces a biomechanical model was developed. In the model the human trunk, neck and head, the legs, and the arms are represented by 27 rigid bodies. An additional body simulates the vibrating vehicle or machinery. The bodies are connected by visco-elastic joint elements. In total 106 force elements imitate the trunk, neck, and leg muscles. The motion equati…(more)
