| Abstract: | The transient dynamic method, which can calculate the crankshaft system forced vibration is introduced. An engine is taken as an example to study the resonance amplitude under critical speed as well as torsional vibration subsidiary stress of different part of its crankshaft. Moreover, resonance amplitude of main orders and the maximum stress of torsional vibration are calculated. Comparison between calculation results and experimental results verified that this method is feasible. |
