本文研究液靜壓軸承使用DSI節流器之平台特性,探討DSI節流器設計參數之影響。靜態部分,探討節流部位設計參數,在不同的有效面積比、節流參數比及節流島高度比之設計參數下,分析無因次工作台位移對無因次承載及無因次剛度的靜態反應,並針對節流島高度比的變化加以分析討論。動態部分探討不同的黏度比、供油壓力、靜態承載力、動態承載力之設計參數,對工作台施加步階力及簡諧力,分析並比較個參數對工作台的反應。
DSI valve was published in AD 1964 by Rippel, its spool is composed of two piston head with a combination of the post, before and after the change by the pressure on the piston and DSI different internal flow resistance of the throttle valve , allowing the flow of oil through the DSI after the throttle bearing oil film has a certain stiffness performance, in order to support oil platform hydrostatic bearing. Equality of the equation by the continuous oil pad and compensator traffic can be derived bearing pressure, hydrostatic oil film thickness platforms, oil platform traffic flow with the relationship between static stiffness platform Therefore this study to establish DSI valve and continuous flow of oil hydrostatic equation platform considerations DSI valve used on oil platforms hydrostatic static characteristics.
