Vibration transmission through tails exposed to three vibration magnitudes (1 g, 5 g, and 10 g r.m.s.) at six frequencies (32 Hz, 63 Hz, 125 Hz, 160 Hz, 250 Hz, and 500 Hz) was measured using a laser vibrometer. A mechanical-equivalent model of the tail was established on the basis of the transmissibility data, which was used to estimate the biodynamic deformation and vibration power absorption at several representative locations on the tail. They were compared with those derived from a mechanical-equivalent model of human fingers reported in the literature. This study found that, similar to human fingers, the biodynamic responses of the rat tail depends on the vibration magnitude, frequency, and measurement location. With the restraint method used in this study, the natural frequency of the rat tail is in the range 161\u2013368 Hz, which is mostly within the general range of human finger resonant frequencies (100\u2013350 Hz). However, the damping ratios of the rat tail at the unconstrained locations are from 0.094 to 0.394, which are lower than those of human fingers (0.708\u20130.725). Whereas the biodynamic responses of human fingers at frequencies lower than 100 Hz could be significantly influenced by the biodynamics of the entire hand\u2014arm system, the rat tail biodynamic responses can be considered independent of the rat body in the frequency range used in this study. Based on these findings it is concluded that, although there are some differences between the frequency dependences of the biodynamic responses of the rat tail and human fingers, the rat tail model can provide a practical and reasonable approach to examine the relationships between the biodynamic and biological responses at midrange to high frequencies, and to understand the mechanisms underlying vibration-induced finger disorders.<\/jats:p>","DOI":"10.1243\/09544119jeim419","type":"journal-article","created":{"date-parts":[[2008,11,3]],"date-time":"2008-11-03T23:45:50Z","timestamp":1225755950000},"page":"1127-1141","source":"Crossref","is-referenced-by-count":34,"title":["An investigation on the biodynamic foundation of a rat tail vibration model"],"prefix":"10.1177","volume":"222","author":[{"given":"D E","family":"Welcome","sequence":"first","affiliation":[{"name":"Health Effects Laboratory Division, National Institute for Occupational Safety and Health, Morgantown, WV, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"K","family":"Krajnak","sequence":"additional","affiliation":[{"name":"Health Effects Laboratory Division, National Institute for Occupational Safety and Health, Morgantown, WV, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"M L","family":"Kashon","sequence":"additional","affiliation":[{"name":"Health Effects Laboratory Division, National Institute for Occupational Safety and Health, Morgantown, WV, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"R G","family":"Dong","sequence":"additional","affiliation":[{"name":"Health Effects Laboratory Division, National Institute for Occupational Safety and Health, Morgantown, WV, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"179","published-online":{"date-parts":[[2008,10,30]]},"reference":[{"key":"bibr1-09544119JEIM419","unstructured":"1 Bernard B.
