RELIABILITY ANALYSIS OF A MARINE DIESEL PROPULSION SHAFTING SYSTEM UNDER TORSIONAL AND AXIAL VIBRATIONS

A practical method for reliability analysis of a marine diesel propulsion shafting system under torsional and axial vibrations is presented. The probabilistic cylinder gas and propeller excitations are considered for the purpose of this work. The methods of reliability estimation are based on response surface and Monte Carlo approaches. The response surface representing maximum responses in a shafting system is built in the form of polynomial of different order. Then Monte Carlo simulation is performed with subsequent approximation of the results by one of the Pearson's curves. Finally the failure probability is calculated by numerical integration. A numerical example is given. Proposals are introduced with the aim of improving the existing deterministic design.
