Abstract:With the analysis of torsionvibration in 12V gas engines,  the analysis model of torsion vibration is established and calculated by using AVL Excite designer software, obtaining these results of torsion modes, critical speeds, angular displacement and shear stress.After analyzing of the calculation results, we matches the vibration damperand do contrast by calculation. This analysis shows that the vibration damper meets requirements and thecrankshaftsystem is proved safe and reliable. The research provides a reference for other designs.
