SUMMARY Case nr: 1 92kW@1500RPM... 2 Case nr: 11 92kW@1500RPM-misfire... 9 The following results were obtained: CASE: 1 11 LIMIT ============================================================================ Crankshaft nom. vibr. stress [MPa] * Generator shaft Nom. Vibr. Stress [MPa] * Crankshaft forw end vibratory torque [Nm] * Crankshaft flywh end vibratory torque [Nm] * Crankshaft viscous damper heat load [kw/m 2 ] * ============================================================================= * Calculated values are below adequate limits CONCLUSION: No problems are foreseen from a torsional vibration point of view.
