冲击载荷下高压大排量径向柱塞泵滑靴副磨损特性
Wear Characteristics of Slipper Pairs in High-pressure Large-displacement Radial Piston Pumps Under Impact Loading
摘要
Abstract
To investigate the friction and wear characteristics of slipper pairs in high-pressure and large-displacement radial piston pumps under impact loading,this study established a transient friction wear model for the stator-slipper contact surface using ANSYS Mechanical software with ANSYS parametric design language programming.The dynamic friction wear of stator-slipper pairs is analyzed under varying working pressures,impact pressure amplitudes,and impact pressure times,supplemented by experimental validation.Key findings reveal that during the 0～0.6 s transient phase,wear primarily occurs between the central oil reservoir and pressure-equalizing groove on the slipper surface,accompanied by uneven wear patterns and stress concentration near the pin hole.The average error of relative value between simulation and experimental results is 8.99%.Through orthogonal experiment analysis and Kriging interpolation fitting,the sensitivity hierarchy of wear factors is determined as impact times,impact pressure amplitude and working pressure.Experimental results under three impact times within 60 minutes show a wear volume of 824.1379 mm3,demonstrating significant structural degradation caused by impact loading and validating the predictive capability of the proposed simulation model for slipper pair wear assessment.关键词
