SUMMARY Case nr: 1 110kW@1800rpm, STAND-BY, NO DAMPER... 2 Case nr: 2 110kW@1800rpm, STAND-BY, DAMPER 248* Case nr: 3 110kW@1800rpm, STAND-BY, DAMPER 280* The following results were obtained: CASE: 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 damper heat load [kw/m 2 ] ================================================== * Calculated values are below adequate limits CONCLUSION: Engine shaft and generator shaft nominal vibration stresses are above allowable levels for the case with engine without crankshaft damper. For the case with standard crankshaft damper (248x32) the heat load is above allowable limits. A larger damper (280x40) reduces the heat load to acceptable values.
