Sažetak
The classical approach to the torsional vibration analysis of the marine propulsion plants deals exclusively with steady-state vibration, analyzed in a frequency domain only. However, some phenomena cannot be properly addressed without carrying out the more demanding, transient torsional vibration analysis, performed in the time domain. Examples of such events include passing through a barred speed range, clutching heavy components, and propeller- ice interactions during a voyage on icy seas. In this paper, a mathematical model of transient torsional vibration analysis is presented. The system response is based on the modified standard computer code for torsional vibration analysis, and the time integration of the system response is performed by utilizing a fifthorder and sixth-order Runge-Kutta-Verner algorithm. Example analyses of passing through a barred speed range are also provided and the measurement results compared.
