In this paper, the simulation model of the range extender system is established to calculate the torsional vibration performance of the shafting system, and the calculation results of the speed nonuniformity and torsional vibration amplitude are obtained. After analyzing the influence of shafting structural parameters on vibration results, the design parameters of torsional damper, flywheel, generator rotor and coupling are optimized through grouping calculation and neural network model based on optimization, so as to improve the vibration performance of shafting.
