Material Characterization Data For A Tube-guided SMA Actuator and A Reversible SMA Hinge Actuator

The data file includes the material experiments of the tube-guided SMA actuator and the SMA hinge actuator. All experiments were used for developing phenomenological models which can predict actuators' performance. <strong>(1) Tube-guided SMA actuator:</strong> material characterization experiments were conducted with two types of materials, including a shape memory alloy wire and a PTFE tube. For the SMA, transformation stress tests, Young’s modulus test, transformation temperatures test and force-control tests were performed. For the tube, thermal expansion tests, Young’s modulus test, and some experiments about creep were performed. A Dynamic Mechanical Analyser (DMA) Q800® of TA instruments was used for all tests. <strong>(2) SMA hinge actuator:</strong> two different types of SMA materials were tested, to figure out their torsion performance in different temperatures. Transformation temperature tests, shear Stress-strain tests, etc. were included. A DMA machine and a Differential Scanning Calorimetry Q2000® were used for tests.

本数据集涵盖管导向形状记忆合金（Shape Memory Alloy, SMA）执行器与SMA铰链执行器的材料测试数据，所有实验均用于构建可预测执行器性能的现象学模型。
(1) 管导向SMA执行器：针对两种材料开展材料表征实验，分别为形状记忆合金丝与聚四氟乙烯（PTFE）管。其中针对SMA开展了相变应力测试、杨氏模量测试、相变温度测试及力控实验；针对PTFE管开展了热膨胀测试、杨氏模量测试以及若干蠕变相关测试。所有测试均采用TA仪器公司的动态力学分析仪（Dynamic Mechanical Analyser, DMA）Q800®完成。
(2) SMA铰链执行器：测试了两种不同类型的SMA材料，以探究其在不同温度下的扭转性能，实验涵盖相变温度测试、剪切应力-应变测试等内容。测试采用动态力学分析仪（DMA）与差示扫描量热仪Q2000®完成。
