【摘要】 本文用有限元法对双列进油式位移敏感内部节流静压轴承包括动压效应在内的静态特性进行了数值分折(四垫、四腔式)和试验研究(四垫式),讨论了承载量、静刚度、流量、摩擦转矩和偏位角等性能的特点,主要参数的选择及加载角的重要性并对已有的垫式解析公式进行了验证和修正。更多还原

【Abstract】 In this thesis, the finite element numerical analysis about the performances, such as load carrying capacity, static stiffness, oil flow, friction moment and attitude angle, of a four-pad and a four-pocket hydrostatic journal bearings with position-sensing inside restrictors with double row of the feed pockets is presented. The hydrodynamic effect caused by the journal rotation is considered. The test measuring the above-mentioned performances of a four-pad bearing is conducted.更多还原
