The rat tail model has been used to examine the mechanisms of vibration induced finger disorders: To help clarify whether the tail model can provide a good simulation of finger vibration exposure, this study investigated the biodynamic foundation of the rat tail model using a mechanical-equivalent model established based on the vibration transmissibility measured on the rat tail. The mechanical model was used to estimate the natural frequency, damping, dynamic deformation and vibration power absorption intensity of the rat tail, which is directly associated with the dynamic stresses/strains inside the rat tail. The rat tail vibration power absorption intensity was compared with those of the fingers that were estimated from a reported hand-arm system mechanical model. This study found that the basic trend of the rat tail biodynamic response in the frequency domain different from that of the human fingers. This suggests that the frequency dependencies of their biological effects may not be directly comparable. However, knowledge of the rat tail biodynamic responses may be used to examine the relationship between biodynamics and health effects.
