ON CRANKSHAFT FILLET STRESSES OF MARINE DIESEL ENGINES

The author describes how the crankshaft fillet stresses are measured using FM radio link strain telemeter. The results of the measurements are summarized as follow; 1) When the additional stress by resonance is smaller, there is good agreement between the measured fillet stresses and calculated ones which are computed considering the resilience of main bearings. 2) The alternating bending stresses were found on fillet at the resonance of torsional vibration. 3) On large two stroke cycle engine crankshaft alternating bending stresses were found at the resonance of axial vibration. And the mode curve estimated from the measured stress differ from the one calculated theoretically. 4) Axial vibration damper is effective to reduce the bending stress induced by axial vibration, but ineffective by torsional vibration.
