摘要

基于脉搏图像传感器的结构与工作原理

应用有限元软件ABAQUS

建立脉搏触压觉模型

模拟中医切脉时的触压觉。利用柔性橡胶薄膜模拟手指切脉

并对其进行离散化处理。通过对传感器探测触头施加不同的切脉压力

分析不同切脉压力下橡胶薄膜的受力变形情况。选取参考单元格

根据其面积变化提取脉搏波形

并在时域内提取脉搏信号的特征参数。通过对不同切脉压力下脉搏信号特征参数进行分析发现

当切脉压力为12 N时所获得的波形最佳。该工作为脉象属性的进一步研究奠定了基础。

Abstract

Based on the structure and working principle of the pulse image sensor

the touch-pressure mechanical model is established by the finite element analysis software ABAQUS to simulate the touch-pressure sensation of the traditional Chinese medical pulse-taking.The flexible rubber film is discretized using the ABAQUS to simulate the finger pulse-taking.The forced deformation of the rubber film under different pulse-taking pressure is estimated.The reference element lattice is selected and the pulse waveforms are extracted depending on the area change of the reference element lattice.The characteristic parameters in time domain are obtained from the pulse signals.According to the analysis of the characteristic parameters under different pulse-taking pressure

it has revealed that the best pulse waveform can be obtained when the pulse-taking pressure is 12 N.This work has laid a foundation for the further study of the pulse condition attribute.
