Optimal Tuning Method of Ships System by Means of Pneumatic Tuner of Torsional Oscillations

Jaroslav Homi¹in, Peter Ka¹¹ay

Drives of mechanical systems consist of driving machines and gearing mechanisms connected together by means of shafts and couplings. With regard to the dynamics it is possible to say that every driving mechanism is a system, which is able to oscillate. Especially piston machines are able to create dangerous and harmful torsional oscillations, vibrations, as well as noisiness.
Important task of designer is reduction of torsional oscillations in mechanical system. Presently this problem is solved predominately with a suitable adjustment of dynamic properties of flexible shaft couplings with regard to the dynamic properties of given system. It means that every torsionally oscillating mechanical system needs to be tuned suitably. The main purpose of this paper is presentation of controlling possibilities of dangerous torsional oscillations of mechanical systems by means of a new method, i.e. its optimal tuning by means of pneumatic coupling with self-regulation, developed by us.

Keywords: dangerous torsional oscillations, tuning of mechanical system, behaviour of optimal tuning of the system, pneumatic coupling with self-regulation - pneumatic tuner
