摘　　要：扭矩脉动是导致内曲线马达产生振动和噪声的主要原因之一。为降低扭矩脉动,设计了U形阻尼槽配流盘;以马达柱塞腔流量压力脉动为基础,建立了阻尼槽配流面积变化及马达扭矩脉动的理论模型。基于AMESim平台建立了内曲线马达动态仿真模型,并采用响应面法对U形阻尼槽进行了参数优化。结果表明:扭矩脉动与U形槽结构参数间存在多种影响机制;相比无阻尼槽,优化U形槽后的配流盘可以使马达扭矩脉动程度降低44.55%。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.
