一、前言所谓定量供油静压支承就是分别向支承的每个油腔直接供给恒量的压力油,以支承载荷。定量供油静压支承以其结构简单(即容易设计、计算和制造)、性能可靠(动态稳定性好)、无多余流量(即节省能源)等优点,得到了比较广泛的应用。在定量供油静压支承系统中,油液的流量对系统的静态特性、动态稳定性和动态幅—频特性有相当重要的影响,也就是说油液流量是定量供油 First, the foreword The so-called quantitative static pressure oil supply is to support each of the oil chamber to provide a direct supply of constant pressure oil to support the load. Quantitative oil-filled hydrostatic support with its simple structure (that is, easy to design, calculation and manufacturing), reliable performance (good dynamic stability), no excess flow (ie, save energy), has been more widely used. In the static supply of static oil supply system, the fluid flow on the system’s static characteristics, dynamic stability and dynamic amplitude-frequency characteristics have a very important impact, that is, the oil flow is quantitative oil supply
