Abstract
This study investigates the overlap of the spherical port plate as a key parameter to reduce hydraulic shock and noise during high-to-low pressure transitions in a bent-axis piston motor.Using CFD simulations analyzes the effects of overlap from-0.5°to 4°(covering negative,zero,and positive overlap)on pressure pulsation,flow pulsation,and volumetric efficiency.The results show that increasing negative overlap improves transition smoothness,but significantly reduce the motor's volumetric efficiency.Conversely,positive overlap enhances volumetric efficiency;however,it intensifies pressure pulsation in the piston chambers.A detailed analysis within the 2°～3°range,combined with noise testing,identifies 2.8°as the optimal overlap.At this setting,both pressure and flow pulsation rates are significantly reduced.Measured noise decreases by 0.7 dB compared to the initial design,achieving an effective balance between low noise and high efficiency.关键词
