Abstract The present study proposes an analytical methodology to estimate the variable loads applied to the vanes of balanced vane pumps. The dissertation is adopted to detail the nature of the different time-varying excitations that load the machine and to define their analytical calculation on the basis of vane geometry, cam ring profile and working conditions. In this context, a dimensional reduction is proposed in order to highlight how the pump geometrical parameters affect each single force component and how they may be used to modify the ratio between each load contribution. A comprehensive overview of the mutual interconnections between time-varying loads and the pump design is provided by means of a parametric study involving vane design parameters, pump displacement and cam ring shape. Admissibility of the pump geometry is verified throughout the entire study. The results show that, given the cam ring shape, the vane design significantly influences the radial loads, which may also reach negative values and promote the vane detachment.

平衡叶片泵中叶片径向载荷的分析测定

摘要 本研究提出了一种分析方法来估计施加到平衡叶片泵叶片上的可变载荷。该论文详细介绍了加载机器的不同时变激励的性质，并根据叶片几何形状、凸轮环轮廓和工作条件定义了它们的分析计算。在这种情况下，为了突出泵的几何参数如何影响每个单独的力分量以及如何使用它们来修改每个负载贡献之间的比率，提出了降维的建议。通过涉及叶片设计参数、泵排量和凸轮环形状的参数研究，全面概述了时变负载与泵设计之间的相互联系。在整个研究过程中验证了泵几何形状的可接受性。结果表明，给定凸轮环形状，叶片设计显着影响径向载荷，径向载荷也可能达到负值并促进叶片脱离。
