1单向阀的设计与仿真摘要：本文首先是在同种规格油压单流阀设计的基础上，充分考虑到水介质的低粘度、易腐蚀等理化特性，对单向阀进行初步结构设计。在单向阀存在的关键技术难点的基础上提出了解决问题的办法。其次，对单向阀的静动态特性进行仿真研究，分析阀的结构参数对阀整体综合性能产生的影响，优化阀的结构参数，并运用软件在不同压力流量下进行仿真分析。 然后，对单向阀的关键零部件进行可靠性分析，建立设计的可靠性数学模型并优化各个相关的参数。本文介绍了一种模糊可靠性模型，并把模型应用于液压控制单向阀当中，对单向阀的卸荷功能做可靠性分析，并计算出其可靠度。期望能从设计上提高阀的可靠性，继而提高整个液压系统的可靠性。 最后，搭建试验系统，提出液压系统中单向阀的卸荷试验原理和试验方法，并对所研制的单向阀进行静、动态特性试验以及噪声试验研究，总结该设计的单向阀中可能存在的问题并提出改进方案。 关键词：单向阀；可靠性分析；结构设计；仿真；改进方案Abstract：This article is first in the same specification On the basis of fully considering the low viscosity of water medium,Corrosion and other physical and chemical characteristics, the one-way valve for the preliminary structural design. On the basis of the key technical difficulties of the one-way valve, the solution is proposed. Secondly, the static and dynamic characteristics of the one-way valve were simulated to analyze the influence of the structural parameters on the overall comprehensive performance of the valve, optimize the structural parameters of the valve, and use the software in different pressure flow simulation analysis.Then, the key parts of the one-way valve reliability analysis, the establishment of the reliability of the design mathematical model and optimize the relevant parameters. In this paper, a fuzzy reliability model is introduced, which is applied to hydraulic control check valve. The reliability of unloading function of check valve is analyzed and its reliability is calc...
