INVESTIGATION OF VARIOUS FACTORS INFLUENCE ON DYNAMIC LOAD OF MECHANICAL SYSTEM BY PNEUMATIC COUPLING APPLICATION
Journal Title: Scientific Journals of Silesian University of Technology. Series Transport - Year 2012, Vol 2012, Issue 76
Abstract
In order to tuning or continuous tuning of torsional oscillating mechanical systems (TOMS) during their operation we apply the pneumatic flexible shaft couplings in these systems. By appropriate gaseous medium pressure change in given couplings we change their torsional stiffness and thus the dynamics of the whole system too. Rapid gas pressure increase in the pneumatic coupling during system operation can under certain conditions excite additional dynamic load, what we in final consequence understand as an external faulty event of the system. Therefore, the objective of this paper will be the investigation of various factors influence (viscous damping coefficient, inflation time, twist angle of the coupling and mass moment of inertia of the load) on given faulty event of the system, based on measurements and mathematical modeling.
