AB Volvo Penta carries no responsibility for input data originating from other than Volvo Penta products. Therefore, please check input data for this calculation carefully. SUMMARY Case nr: 1 89kW@18rpm, FLYW=1.2kgm2, Damper 248* Case nr: 2 89kW@18rpm, FLYW=2.6kgm2, Damper 248* Case nr: 3 89kW@18rpm, Flyw=1.2kgm2, No Damper Case nr: 4 89kW@18rpm, Flyw=2.6kgm2, No Damper 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: Case 1 No problems are foreseen from a torsional vibration point of view. Case 2 The stress in the generator shaft is above reccomended limit. Case 3 The speedrange must be avoided. Case 4 The stress in the generator shaft is above reccomended limit.
