Abstract

To balance the inertia force and torque of a 3-cylinder engine is more difficult than a 4-cylinder engine due to its structural characteristics. The torsional vibration of crankshaft system is much more difficult to control, which seriously affects the NVH performance during the engine running. In order to improve the torsional vibration of crankshaft and the NVH performance of engine, the torsional vibration of a 3-cylinder engine was analyzed and predicted by onedimensional and threedimensional multibody simulation system, the analysis results were then verified through the experiment, and the torsional vibration characteristics and torsion control are further studied. The results show that the real working state of engine can be redescribed fairly well by the digital model and hence the nonbearing crankshaft torsional vibration damper can be used in the crankshaft system so as to keep the engine torsional vibration at a good level.
