| Abstract: | Theories of flexible multi-body dynamics and MSC.Adams software of multi-body dynamics were applied to make analysis of gyro effect on crankshaft system of a marine diesel engine.The influence of gyro effect on stress and fatigue life of crankshaft system due to coupling of hull longitudinal swing with crankshaft rotation was analyzed under the working condition of 60° cylinder cut-in angle.The research provides basis for the design work. |
| Keywords: | crankshaft flexible multi-body dynamics gyro effect fatigue life |
