摘要/Abstract

摘要：

针对中国体征假人胸部生物保真度的评价指标，提出了一种考虑生物组织黏性作用的胸部力学响应通道缩放方法。根据人体黏弹性生物特征，引入等效黏度C_E的概念，对现有的弹性缩放方法进行黏性修正。通过引入黏度修正因子ξ和速度损耗因子e，建立一种非线性通道缩放表达式。该方法计算得到的最大冲击力和最大压缩量的平均误差分别为8.77%和5.55%，相较于原方法分别降低了3.84%和0.37%。仿真结果表明，该方法对冲击力修正有效。

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
