380吨新型钳夹车液压举升系统分析

Analysis for the Hydraulic Raising System of the New 380t Clampig Rolling Stock

研究了３８０吨新型钳夹车举升系统的举升过程，利用能量法对其举升原理及可靠性进行了严格的分析论证．最后给出了油缸压强及举升高度等之间的曲线。

Presents the theoretical analysis for the hydraulic raising system of the new 380 t clamping rolling stock based on the energy principle.Some examples demonstrate its reliablility,and some important corresponding curves describe their relationships among the hydraulic pressure,raising altitude and piston travel as well.
