Compression garments due to their numerous medical applications have been recently attracted to be mechanically analyzed for their compression mechanism. Predicting the pressures applied to musculoskeletal tissues supported by these garments is a good solution for doing such analyzing which could be simply achieved by the help of finite element method. In this paper, the main aim was investigating the structural effect of knitted compression garments used for supporting the body lower-limb musculoskeletal system. Compression garments of weft knitted rib structure containing elastane yarn were prepared according to the leg’s dimensions of a healthy 27-year old person. Using Kikuhime measuring device, experimental values of the applied pressure were measured in order to be compared with theoretical results. For developing a three-dimensional biomechanical model for the leg system supported by compression garment, images form computed tomography scanning methodology was used. Tensile properties of an elastane yarn as the basis for studying the compression garment’s mechanical behavior were experimentally measured and then simulated in Abaqus software as a linear viscoelastic material. The results were then applied to multi-scale modeling technique in order to simulate mechanical behavior of the knitted fabric and the compression garment thereof. Combination of both experimental and theoretical results was applied to simulate interactions between the leg and the compression garment. The results indicated that the pressure values simulated by finite element method were predicted with the maximum mean error of 19.64 % and total error mean of 12.29 % compared to experimental results. Small difference between the measured and simulated values was observed for tibia and fibula because of their low soft-tissue volume. The proposed model enables the specialists to present compression garments based on the patient’s needs and physician prescription which generate the optimal treatment.

由于其在医学上的众多应用，近来吸引了压缩服装以对其压缩机制进行机械分析。预测施加到这些衣服所支撑的肌肉骨骼组织上的压力是进行此类分析的好方法，可以通过有限元方法轻松实现。在本文中，主要目的是研究用于支撑人体下肢肌肉骨骼系统的针织压缩服的结构效果。根据健康的27岁成年人的腿部尺寸，准备了包含弹性纤维的纬编罗纹结构压缩衣。使用菊姬测量装置，测量所施加压力的实验值，以便与理论结果进行比较。为了开发由压缩服装支撑的腿部系统的三维生物力学模型，使用了计算机断层摄影扫描方法的图像。实验测量了弹性纤维的拉伸性能，作为研究压缩服装机械性能的基础，然后在Abaqus软件中将其作为线性粘弹性材料进行了模拟。然后将结果应用于多尺度建模技术，以模拟针织物及其压缩服装的机械性能。实验和理论结果的结合被用来模拟腿和压缩服装之间的相互作用。结果表明，用有限元方法模拟的压力值的最大平均误差为19.64％，总误差平均值为12。与实验结果相比，降低了29％。由于胫骨和腓骨的软组织量较小，因此在测量值和模拟值之间观察到很小的差异。所提出的模型使专家能够根据患者的需求和医生的处方来展示压力衣，从而产生最佳治疗效果。
