基于NSGA-Ⅱ的滑油泵叶轮结构优化设计
Optimal Design of Slip Oil Pump Impeller Structures Based on NSGA-Ⅱ
摘要
Abstract
Slip oil pumps often needed to operate stably at high altitude and under low pressure conditions,which often led to cause problems such as insufficient oil supply and reduced efficiency.In order to get the best performance of the pump to meet the design requirements,this paper taken the impeller of a helicopter oil pump as the research object and to optimise the structure.The efficiency and lift of two typical working conditions at high altitude were selected as the optimisation targets,and the NSGA-Ⅱ was used to optimise the geometric parameters of the oil pump impellers,and the efficiency and lift of the oil pump before and after the optimisation were compared and analysed.CFD fluid simulation and experimental methods were used to verify the optimisation results.The results show that:the selected optimization parameters have a greater impact on the performance of the slip oil pumps,near the optimized slip oil pump vane positions the flow is more smooth,the high and low pressure areas of the excessively smooth,the energy loss is smaller,and the possibility of cavitation is reduced.The optimized slip oil pump design point lift increases 2.6 m,the efficiency increases 2.86%.关键词
