New Ways of Controlling Dangerous Torsional Vibration in Mechanical Systems
Abstract
In general terms the mechanical systems (MS)mean the systems of driving and driven machines arranged
to perform the required work. We divide them into MS operating
with constant speed and MS working within a range
of speed. In terms of MS dynamics we understand the system
of masses connected with flexible links between them,
i.e. systems that are able to oscillate. Especially piston machines
bring heavy torsional excitation to the system, which
causes oscillation, vibration, and hence their noise. Based on
the results of our research, the torsional vibration control
as a source of given systems excitation, can be achieved by
application of pneumatic couplings, or pneumatic tuners of
torsional vibration. Existence of pneumatic couplings and
pneumatic tuners of torsional vibration developed by us,
creates the possibility of implementing new ways of torsional
oscillating mechanical system tuning. Based on the
above, the aim of the article is to present new ways of dangerous
torsional vibration control of mechanical systems by
application of pneumatic couplings and pneumatic tuners of
torsional vibration developed by us.
