Herein, a new torsional device based on shape memory alloy elements and operating as torque limiter is presented. It consists of a set of pseudoelastic NiTi tapes working in series configuration. The tapes are assembled radially with respect to the rotational direction and work sequentially in beam-like bending mode. The trend of the resulting torque may span from pulsating to continuous by changing the number of tapes. Furthermore, the use of NiTi material enables a temperature-dependent response. Due to the particular mounting, the flag-shaped pseudoelastic mechanical behavior typical of NiTi is partially hidden; however, the use of pseudoelastic elements provides a stable cyclic response and enables the possibility to tune the output torque.

基于镍钛伪弹性带的扭矩限制器研究

本文介绍了一种基于形状记忆合金元素并用作扭矩限制器的新型扭转装置。它由一组串联配置的伪弹性 NiTi 胶带组成。胶带相对于旋转方向径向组装，并以梁状弯曲模式顺序工作。通过改变磁带的数量，产生的扭矩的趋势可能会从脉动变为连续。此外，使用 NiTi 材料可以实现与温度相关的响应。由于特殊的安装方式，NiTi 典型的旗形伪弹性力学行为被部分隐藏；然而，伪弹性元件的使用提供了稳定的循环响应，并可以调整输出扭矩。
