Abstract

Considering the errors of the restrictor and the hole in the form of ellipse, the influences of assembly position of annular slit restrictor and the errors value on stiffness coefficient and damping coefficient of hydrostatic guideways are investigated. It is shown that assembly position of the restrictor have great influence on dynamic coefficients of hydrostatic guideways. Moreover, the greater of the errors value, the greater of influence of assembly position on the hydraulic resistance of the restrictor, stiffness coefficient and damping coefficient. Under the same conditions, the influence of assembly position on damping coefficient is greater than on stiffness coefficient. Improving the machining accuracy of the restrictor or the hole can reduce the influence of assembly position on dynamic performance of hydrostatic guideways. During the process of adjusting the restrictor should take into account the impact of assembly position.
