【摘要】 针对目前水压阀中微造型的设计,研究微造型对于流场声压的影响。了解水压阀噪声产生因素,应用有限元的方法针对水压阀阀道内流场的影响进行仿真分析,从声压和速度两个方面综合考虑考虑和分析,对比带有微造型和不带微造型的两种模型,得到一些有用的结论:水压阀的表面微造型会增加阀的空化噪声。更多还原

【Abstract】 Aiming at the pressure valve in the shape of micro-design, research and modeling for micro flow field sound pressure impact. Learn hydraulic valve noise factor, finite element method simulation analysis of influence within the hydraulic valve for channel flow field, from the pressure and velocity into account two aspects consideration and analysis, modeling and comparison with the micro-micro without the shape of the two models, some useful conclusions: surface texturing increases the pressure valve cavitation noise valve.更多还原
