Flow Field Analysis and Optimization of Automotive Steering Pump Relief Valve

借助流体分析软件Fluent构建了关于溢流阀的内流域模型,并基于该模型建立了有限元分析模型,通过设定相关的参量实施了多次迭代计算得到基本性能参数。借助分析结果改进了既有结构,并采用相同的方法对两种改进结构实施了性能分析,通过分析发现,在速度场及压力场等方面,优化后的结构有着显著改善。通过本文的研究,对溢流阀结构和性能进行了系统探索,获得了预期的研究成果。

Based on the fluid dynamics simulation software named Fluent established a physical model of re- lief valve in the pump basin, and established finite element model based on the basic theories and methods of fluid dynamics, also implement the boundary definition and iterative calculation. With the help of analy- sis results, improved the existing structures.And analysised the two structures used the same method. Through the analysis the results, In terms of the velocity and pressure fields, the optimized structure has been improved significantly. Through the study of this paper, research and improved the relief valve struc- ture systemlly, and obtained the expected results.
