Jul 01, 2014 · 1 Introduction. Exposures to WBV are evident in the industrial world, in particular for earth-moving equipment including off-road vehicles. WBV comprises mechanical vibration or shock transmitted to the body as a whole (Griffin, 1990).When WBV is transmitted to the human body at the natural frequency of the body as a whole or of its individual parts a condition …
