Determining Optimum Air Pressure Value in Pneumatic Flexible Shaft Coupling

Abstract

At our workplace, we deal with research in the broad field of machine parts and mechanisms. It is very appropriate and needful to utilize the knowledge gained from our extensive research also in an educational process. Therefore, the aim of this paper is to present one of our educational activities, based on the research in the field of continuous tuning of mechanical systems in terms of torsional vibration magnitude using pneumatic flexible shaft couplings -pneumatic torsional vibration tuners. The main task of the activity -laboratory measurement, prepared for students in the subject "Design of machines and machine elements" is to determine experimentally an optimum air pressure value in a pneumatic coupling, which is mounted in an experimental mechanical system of piston compressor drive for a given operating mode of the system. So the students can apply gained knowledge from multiple subjects, especially from subjects "Dynamics" and "Machine parts" in practice and also gain the practical experience.
