| Abstract: | The torsional vibration model of a diesel crankshaft assembly including the torsional vibration damper and flywheel was built by employing the dynamics method. In order to find the best suitable natural frequency of torsional vibration damper for crankshaft, the optimization of torsional vibration damper were performed in detail. The torsional behavior of the crankshaft assembly with the optimal torsional vibration damper was simulated. The result shows that the torsional vibration of the cranktrain is acceptable and satisfactory. |
