Vibration　problem　has　been　destroying　the　harmony　between　human　being　and　nature.　In　order　to　analyze　the　effect　of　vibration　on　human　body,　twenty　subjects　were　exposed　to　random　vibration　in　fore-and-aft,　lateral　direction　in　standing　position.　The　accelerations　at　head,　abdomen　and　leg　of　each　subject　were　measured.　The　response　was　analyzed　by　means　of　acceleration　sat　the　measured　points　and　their　Fourier　spectra　and　transfer　function.　The　results　show　that　the　response　curves　of　all　of　the　subjects　in　the　same　direction　are　substantially　the　same.　The　resonance　frequencies　decreased　in　different　degree.　A　principal　resonance　peak　around　0.6Hz　at　different　body　parts　of　the　same　subject.　The　research　results　can　provide　a　reference　for　human　body　modeling　and　human　comfort　evaluation.
