摘要

本文建立了一个完整、准确的典型变量叶片式油泵的数学模型,研究了该泵的工作性能。首先,基于泵的几何设计和动力学分析,建立了详细的理论模型。其次,对所建立的模型进行数值仿真,并在实际泵系统上进行实验,分析主要功率损失因素,建立完整的高精度模型。最后通过数值模拟与实际试验对比,验证了采用完整泵模型估计的泵性能。

Mathematical modeling of a variable displacement vane pump for engine lubrication
This paper developed a complete and accurate mathematical model for a typical variable displacement vane-type oil pump to investigate the working performance of the pump. Firstly, the detailed theoretical model was built based on pump's geometric design and dynamic analyses. Next, numerical simulations with the constructed model and experiments on the real pump system were carried out to analyze the main power loss factors in order to develop the complete model with high accuracy. The estimated pump performance using the complete pump model was finally verified by numerical simulations in comparison with the practical tests.
