摘要

流变学和粘弹性材料研究是工程学和生物物理系统研究不可分割的一部分。组织流变学甚至被用于癌症和其他疾病的研究。然而,流变仪的成本只有大专院校和研究实验室才能承受。即使能买到流变仪,它也很笨重,校准也很复杂,因此其用途仅限于实验室本身。本文介绍的设计成本不到专业流变仪的十分之一。该设计还便于携带,是向中学生介绍粘弹性以及在现场获取流变数据的理想解决方案。

A Torsion-Based Rheometer for Measuring Viscoelastic Material Properties.

Rheology and the study of viscoelastic materials are an integral part of engineering and the study of biophysical systems. Tissue rheology is even used in the study of cancer and other diseases. However, the cost of a rheometer is feasible only for colleges, universities, and research laboratories. Even if a rheometer can be purchased, it is bulky and delicately calibrated, limiting its usefulness to the laboratory itself. The design presented here is less than a tenth of the cost of a professional rheometer. The design is also portable, making it the ideal solution to introduce viscoelasticity to high school students as well as for use in the field for obtaining rheological data.
