Measurement of the frequency response of man exposed to vibration

Despite much research into human response to whole-body vibration, there exists only a limited basic understanding - insufficient for any reliable prediction of response to a particular vibrational environment. It is argued that a viable explanation of human response to vibration is dependent on an adequate understanding of the complex biomechanical behaviour of the body. Further, knowledge of the degree of linearity of biomechanical frequency response is important if behaviour is to be understood and capable of prediction or application to system design. The aim of the research was to investigate the linearity of response and develop a reliable technique for the investigation of biomechanical response to vibration, the technique being simple and safe to apply to individuals in a variety of postures and eliciting results relevant to practical situations. A further aim was to investigate how far posture might modify the biomechanical behaviour [continued]…
