摘　　要：针对传统叶片泵存在的叶片磨损大、易卡死和低速性能差问题,提出一种创新结构的摆动叶片泵。新结构通过叶片摆动将滑动摩擦转变为滚动摩擦,有效改善了叶片受力状况;同时,通过叶片摆动和独特结构,有效解决了传统叶片泵在低速运行时因离心力不足而无法正常工作的问题。详细分析了新结构的特点和工作原理,推导了排量计算公式;通过叶片受力分析和有限元应力场模拟,确定了叶片受力最大的部位,对提高叶片泵的使用寿命和应用范围具有重要意义。Aiming at the problems of large blade wear,easy sticking and poor low-speed performance of traditional vane pumps,this study proposed an innovative structure of swinging vane pumps.The new structure transforms sliding friction into rolling friction through blade swing,effectively improving the blade stress condition.At the same time,through the blade swing and unique structure,the problem that the traditional vane pump can not work properly due to insufficient centrifugal force at low speed is effectively solved.In this study,the characteristics and working principle of the new structure are analyzed in detail,and the displacement calculation formula is derived.Through the blade force analysis and finite element stress field simulation,the most stressed part of the blade is determined,which is of great significance to improve the service life and application range of the blade pump.
