扭辫分析(torsional braid analysis简称TBA)是六十年代初由Lewis和Gillham发明的。十多年来,这种动态力学分析方法在国内外已普遍得到了应用。就国内而言,不少高等院校和科研单位不仅用此作了大量的研究工作,而且仪器已转入商品生产,并实现了全自动化。 Torsion braid analysis (TBA) was invented by Lewis and Gillham in the early 1960s. More than a decade, this method of dynamic mechanical analysis has been widely used at home and abroad. As far as China is concerned, many institutions of higher education and research institutes have not only done a great deal of research on this subject, but also have transferred their instruments to the production of goods and have achieved full automation.
