摘要
本研究的目的是开发一种可靠的摩擦学模型，以便更深入地研究与非特异性下背痛有关的筋膜组织的摩擦行为。通过低频、低负荷往复运动，根据摩擦系数设计并评估了几种模型。研究发现，在 PDMS 上分层模拟筋膜和下层肌肉的两种技术弹性体适合替代模型中的生物组织。研究还考察了摩擦对几何形状的影响，结果表明，无论使用哪种材料组合，接触的一致性越高，COF 越低。最后，还测试了不同分子量和浓度的 HA 的摩擦特性。
Understanding frictional behavior in fascia tissues through tribological modeling and material substitution
The objective of this study is to develop a reliable tribological model to enable a more thorough investigation of the frictional behavior of fascia tissues connected to non-specific lower back pain. Several models were designed and evaluated based on their coefficient of friction, using a low-frequency, low-load reciprocating motion. The study found that two technical elastomers, layered on PDMS to simulate the fascia and underlying muscle, are suitable substitutes for biological tissue in the model. The influence of tribopair geometry was also examined, and the results showed that greater conformity of contact leads to a lower COF, regardless of the material combination used. Finally, the friction properties of HA of various molecular weights and concentrations were tested.
期刊介绍：
The Journal of the Mechanical Behavior of Biomedical Materials is concerned with the mechanical deformation, damage and failure under applied forces, of biological material (at the tissue, cellular and molecular levels) and of biomaterials, i.e. those materials which are designed to mimic or replace biological materials.
The primary focus of the journal is the synthesis of materials science, biology, and medical and dental science. Reports of fundamental scientific investigations are welcome, as are articles concerned with the practical application of materials in medical devices. Both experimental and theoretical work is of interest; theoretical papers will normally include comparison of predictions with experimental data, though we recognize that this may not always be appropriate. The journal also publishes technical notes concerned with emerging experimental or theoretical techniques, letters to the editor and, by invitation, review articles and papers describing existing techniques for the benefit of an interdisciplinary readership.
