Purpose

The usage of pneumatic artificial muscles (PAMs) is becoming increasingly widespread across a variety of industries because of its advantages such as its lightness and its ability to generate a huge amount of force using the fewest components. The purpose of this paper is to develop a piece of hardware to minimize and equally distribute the thermal changes on the surface of a PAM when positioning using PAMs. A classic PAM and a PAM that contains the hardware suggested for tasks, such as the positioning of spoilers decelerating control surfaces for aircrafts, were compared experimentally.

Design/methodology/approach

Rapid thermal changes were detected in the classic PAM, especially at the tip of the PAM. These thermal changes decrease the positioning sensitivity and reliability, thus shortening life span of the PAMs. A component was developed that could create a circulation of air around the tip of the PAM, preventing the temperature increase caused by still air. It is installed inside the PAM and makes it possible to control the pressurized air volume in crucial areas. Shaped as a perforated metal pipe, the component was embedded inside the PAM and effects of this component were investigated.

Findings

The experiment results have shown that, thanks to the system that was developed, cool air that comes from outside is able to reach the tip of the PAM every time, thus keeping regional temperature increase to a minimum. The temperature increase in the pressurized air inlet was minimized by creating a circulation of air in the area.

Originality/value

With this study, the distribution of heat in different areas on PAM was homogenized at a low cost using the component that was developed.

使用气动人工肌肉（PAM）开发新系统以减少扰流板定位过程中的温度升高

目的

气动人造肌肉（PAM）的优点在于它的轻巧性和使用最少的组件产生大量力量的能力，因此在各种行业中的使用正变得越来越普遍。本文的目的是开发一种硬件，以在使用PAM定位时最大程度地减少和均匀分布PAM表面上的热变化。通过实验比较了经典的PAM和包含建议用于任务的硬件的PAM，例如，扰流板的位置使飞机的控制面减速。

设计/方法/方法

在经典PAM中，尤其是在PAM的尖端，检测到快速的热变化。这些热变化会降低定位灵敏度和可靠性，从而缩短PAM的使用寿命。开发了一种组件，该组件可在PAM尖端周围形成空气循环，从而防止由静止空气引起的温度升高。它安装在PAM内，可以控制关​​键区域的压缩空气量。该部件成形为带孔的金属管，被嵌入到PAM中，并研究了该部件的作用。

发现

实验结果表明，借助已开发的系统，每次都可以从外部获得冷空气到达PAM的尖端，从而将区域温度升高保持在最低水平。通过在该区域中形成空气循环，可最大程度地降低加压空气入口中的温度升高。

创意/价值

通过这项研究，使用开发的组件可以低成本将PAM上不同区域的热量分布均匀化。
