A study on Dynamic Characteristics of Flywheel System in Flywheel-type Forage Cutterhead

On the basis of dynamic mathematical model established for flywheel system in flywheel-type forage cutterhead, the response of the system to pulse form unit torque is analysed in this paper. The form of torque function introduced into the system when the system was in working condition was determined through experiments, and the response process of the system to the imput torque functions was studied. Furthermore, mathematical model for the system response was developed. Finally the effects of dynamic para- meters for the system on the rosponse were investigated, according to the equations.
