本文探討閉式靜壓滑軌應用毛細管節流器的特性。滑軌採平軌單列多油腔型式，潤滑油為定壓供油，經過分別的毛細管節流，進入油腔以承載工作台及其負荷。根據流量守恆原理，且假設油腔之間的節流壓力呈線性分佈，建立聯立的流量平衡方程式，求解得到各油腔之壓力，經積分求得靜壓滑軌之承載能力及剛度。並以毛細管節流係數為參數，探討工作台位移率對於承載及剛度的影響。

This study investigates the characteristics of the externally pressurized, multi-recessed, close-type, flat hydrostatic slideways by using the capillary restrictor as compensating elements. The coupled equations of recess pressures are provided according to the balance of flow rate in recess. The load capacity and static stiffness are then obtained by integrations of pressure distribution with solved from coupled flow equations. Furthermore, the influence of displacement rate of working table on load capacity and stiffness is studied for capillary restriction as the parameter.
