液压

The purpose of this thesis is to design an experimental device based on hydraulic servo control to simulate the working state of the jigger air-valve, then to provide auto-control of air-valve with hardware base.

本文旨在设计一种基于液压伺服控制的实验室装置，对跳汰机风阀工作状态进行模拟，从而为风阀自动控制提供硬件基础。

Reduce-box, gear-box, outer joggle pulley and all parts lubrication and hydraulic are both worked according to the required.

9.1.2 减速箱，变速箱，外啮合齿轮等各部分的润滑以及液压油均按润滑表中的要求进行。

When maximum jounce is approached, jounce force and energy are exchanged, at a first stage, with the jounce bumper cushion, then at a predetermined compression, jounce force and energy are exchanged, at a second stage, with the hydraulic jounce bumper.

当最大颠簸逼近的时候，颠簸力与能量在第一级与颠簸缓冲器垫交换，然后以预定的压缩量，颠簸力与能量在第二级与液压颠簸缓冲器交换。

This paper sets up the theories and methods to analyze and simulate kinematics and dynamics characteristics of hydraulic hammers.

Based on the Landaulet study, which was most recently shown at the 2008 Detroit Auto Show last month, the Landaulet is mechanically similar to the Maybach 62S sedan. A major difference is that the Landaulet removes the rear roof module in favor of an electrohydraulically folding roof so "pampered rear-seat passengers" can look at the stars — or be stars — while a chauffeur drives.

Landaulet的机械结构和迈巴赫62S轿车一样，二者主要的差别在于前者去掉了车顶的后半部分而以电子液压折叠顶篷来替代，此举旨在"过分照顾后排乘客"使他门可以在由专职司机驾车出行时能获得超级明星般的感受——或者是能被当作一个明星来看待。
