This study aimed to formulate a numerical approach (finite element modelling (FEM)) to calculate pressure values generated by compression garments on a compressible limb analogue, and to validate the numerical approach using experimental measurements. Existing models were also compared.
Experimentally measured pressure values and deformation caused by compression bands on a compressible human limb analogue were compared with values predicted using the Young-Laplace equation, a previously formulated analytical model and the FEM.
The FEM provided greater accuracy in predicting the pressure generated by compression bands compared to existing models. The FEM also predicted deformation of the limb analogue with good agreement relative to experimental values.
It was concluded that modelling the non-uniform manner in which the way a limb analogue is compressed should be incorporated into future modelling of the pressures generated by compression garments on a compressible limb analogue.

本研究旨在制定一种数值方法(有限元建模(FEM)),以计算压缩衣物在可压缩肢体模型上产生的压力值,并通过实验测量来验证该数值方法。同时还对现有模型进行了比较。
将实验测量得到的压缩带在可压缩人体肢体模型上产生的压力值和变形,与使用杨氏-拉普拉斯方程、先前制定的解析模型和有限元建模预测的值进行比较。
与现有模型相比,有限元建模在预测压缩带产生的压力方面具有更高的准确性。有限元建模还预测了肢体模型的变形,与实验值具有良好的一致性。
得出的结论是,在未来对压缩衣物在可压缩肢体模型上产生的压力进行建模时,应纳入对肢体模型压缩方式不均匀性的建模。
