Abstract

Abstract:

This paper discusses the evaluation indices of the thoracic biofidelity of the Chinese anthropomorphic test device（ATD） and proposes a scaling method for the chest mechanical response that considers the effect of biological viscosity. Based on the viscoelastic biological characteristics of the human body， the concept of equivalent viscosity C_E is introduced to correct the current elastic scaling method for viscosity. By introducing the viscosity correction factor ξ and the velocity loss factor e， a nonlinear channel scaling expression is established. The average errors of the maximum impact force and maximum compression calculated by this method are 8.77% and 5.55%， respectively， which are 3.84% and 0.37% lower than those of the original method. The simulation results show that this method effectively corrects the impact force.

Key words: engineering bionics, anthropomorphic test device, chest impact response corridor, viscoelastic scaling method
