摘要: 射流管式伺服阀具有可靠性高、抗污染能力强的优势。以某射流管式伺服阀为研究对象,研究了阀体、马达壳体和马达螺钉组件的静强度。由于射流管式伺服阀的结构较复杂,使得强度试验中油压的加载位置难以精确控制,因此,采用CAD软件CATIA建立了阀组件的几何模型,然后利用Abaqus平台得到了不同工况下的静强度分析结果。分析了模型中各部件的应力和位移分布在不同的油压载荷下的变化规律。

Abstract: Jet pipe servo valve have the advantage of high reliability and anti-polution capability.In this paper,static strength of main components of jet pipe servo valve was researched.Due to the complex structure,the loading position of oil pressures are difficult to control accurately in strength test.For that reason,a three-dimensional model of valve module was established using CATIA software and the FEA was performed on the Abaqus platform in this paper.Based on the comparative analysis of different oil pressures,we also analyzed the change of stress distribution and displacement distribution.
