Study of the effect of temperature on the positioning accuracy of the pneumatic muscles

Abstract

Abstract. The article concerns experimental studies of the effect of temperature on the positioning accuracy of pneumatic muscles. It presents results of experimental studies in the form of thermal images from thermal imaging camera. Pneumatic artificial muscles have unique operational characteristics and because of that they are used in industrial production processes, where classic drives do not work. During operation of muscles with large frequencies above 60 Hz, one can observe a significant increase in temperatures on the bladder surface. The article concerns a study aimed at the determination of the maximum temperature which can be achieved and whether it affects the accuracy of their positioning.

Simulation research of the temperature distribution during face milling

“…Fast and accurate temperature measurement is of particular importance for the use of this information to monitor the condition of the cutting edge. Elevated workpiece temperature in the machining process primarily affects tool wear, but can also lead to a reduction in the performance of machine parts, machine tools, pneumatic valves, non-contact face seals [6,7]. In addition, an increase in workpiece temperature during cutting can reduce the accuracy of the machining process related to the thermal expansion of the workpiece material and lead to changes in the structure of the surface layer.…”
