Torque Pulsation Improvement in Cam Lobe Motor with Distributor Damping Structure
Torque pulsation stands as one of the principal causes of vibration and noise in cam lobe motors.A U-groove distributor plate has been designed to attenuate torque pulsation.Based on the flow-pressure pulsation of the motor's piston chambers,a theoretical model is established for the variation of damping slot distribution area and motor torque pulsation.Utilizing the AMESim platform,a dynamic simulation model of the cam lobe motor is established,and the response surface methodology is employed for parameter optimization of the U-groove.The results demonstrate that torque pulsation is influenced by multiple mechanisms associated with the structural parameters of the U-groove.Compared to the undamped slot,the optimized U-groove distributor plate has achieved a 44.55% reduction in torque pulsation level.
