With drive line of a series-parallel hybrid electric bus as research object, a torsional vibration mechanics& control model is built with software AMESim, and a vehicle operation process incorporating various operating conditions is designed to calculate the torsional vibration responses of the drive line in those operating conditions. Through response sensitivity analysis, the main factors affecting torsional vibration of critical system components are derived. The stiffness parameters of the vibration damper in the drive line are optimized with the maximum twist angle of the dampers as the objective function. The natural characteristics of the optimized drive line is calculated separately under various operational modes, which are used for resonance check with excitation signals. The torsional vibration response of the optimized system after is compared with that without optimization, which shows that the expected vibration damping effect is achieved with this optimization.
