气动人造肌肉是一种气压驱动的橡胶致动器。与电动执行器和流体动力气缸相比，它重量轻且功率密度高。此外，由于其具有良好的柔韧性，因此显示出与人体的高度相容性。作者开发了一种直纤维型气动人工肌肉（SF-ARM），与广泛使用的 McKibben 型人工肌肉相比，具有高输出和收缩量。尽管已经检查了 McKibben 型的疲劳寿命，但尚未对 SF-ARM 进行类似的研究。在本研究中，进行了SF-ARM的寿命延长、高变形橡胶材料的开发以及SF-ARM的长径比的检查。首先，通过有限元法进行变形分析，确定橡胶材料的目标伸长值并开发合适的材料。接下来，通过改变长径比来减小橡胶材料的应变，从而测量疲劳寿命和收缩特性。结果显示了人造肌肉的寿命和形状之间的关系。我们证明，根据应用，可以通过操纵 SF-ARM 的形状和尺寸来选择寿命与收缩力和比率之间的关系。
A pneumatic artificial muscle is an air pressure-activated rubber actuator. It is lightweight and high in power density compared to motorized actuators and fluid-powered cylinders. In addition, it shows high compatibility with the human body because it has good flexibility. The authors have developed a straight-fiber-type pneumatic artificial muscle (SF-ARM) with high output and contraction amounts compared to those of the widely used McKibben-type artificial muscle. Although the fatigue life of the McKibben type has been examined, similar studies have not yet been performed for SF-ARM. In this study, the extension of the lifetime of SF-ARM, development of high-deformation rubber material, and examination of the SF-ARM aspect ratio were performed. First, from deformation analysis by the finite element method, the target elongation value of the rubber material was determined and a suitable material was developed. Next, the fatigue life and contraction characteristics were measured by reducing the strain of the rubber material by changing the aspect ratio. The results showed a relationship between the lifetime and the shape of the artificial muscle. We demonstrate that the relationship between the lifetime and contraction force and ratio, according to the application, can be selected by manipulating the shape and the size of the SF-ARM.
