In this paper, the results of the analysis of the forces acting on vanes in a double-acting vane pump with an integrated electric drive have been presented. In the new motor pump unit, the pump is assembled inside the rotor of the electric motor. A dynamic model representing the vane movement has been developed considering the impact of pressure load distribution, vane support forces and friction forces. The loss of contact between the vane head and the cam ring lead to the noise and reduction of the volumetric pump efficiency. The dynamic model which describes the vane motion and contact between the vane tip and cam ring has been solved using MATLAB software. The influence of load distribution, pump design and operational parameters on the vane dynamics has been analysed.

在本文中，介绍了作用在带有集成电驱动的双作用叶片泵中的叶片上的力的分析结果。在新的电动泵单元中，泵安装在电动机的转子内。考虑压力载荷分布、叶片支撑力和摩擦力的影响，开发了代表叶片运动的动态模型。叶片头和凸轮环之间失去接触会导致噪音和容积泵效率的降低。描述了叶片运动和叶片尖端与凸轮环之间接触的动力学模型已使用 MATLAB 软件求解。已经分析了负载分布、泵设计和操作参数对叶片动力学的影响。
