介绍了一种小型化双向拉伸装置。基于扭转加载设计，减小了装置的总尺寸和重量，同时增加了输出力。由于采用了四个独立的步进电机，该装置在加载过程中可以实现任意的位移比。该装置与激光扫描共聚焦显微镜配合使用，实现了原位力学测试。通过优化十字形试件的原理验证实验，证明所研制的双向拉伸装置适用于双向应力分析的原位测试。由AIP Publishing授权出版。
A miniaturized biaxial tensile apparatus is presented. Based on a torsional loading design, the total dimensions and weight of the apparatus have been reduced, while the output force has been increased. Owing to the use of four independent stepping motors, the apparatus can realize arbitrary displacement ratios during the loading processes. The apparatus is designed to be applied with a laser scanning confocal microscope realizing in situ mechanical tests. Through a proof-of-principle experiment with an optimized cruciform shaped specimen, the developed biaxial tensile apparatus is proved to be suitable for in situ tests of biaxial stress analysis.
