液压缸内渐变节流式缓冲装置的特性分析

Analysis on Characteristic of Gradual Change Throttleable Cushion in Hydraulic Cylinders

介绍了目前在液压缸内普遍采用的缓冲装置和几种接近理论分析的实用缓冲头，并分析了这些缓冲装置的优缺点，在此基础上推出了一种渐变节流式缓冲装置，并应用流体力学的有关知识进行了理论分析。

The writer introduces the cushions commonly used in hydraulic cylin-ders,and introduce several kinds of cushions which are of characteristic in theory,makes an analysis of the merits and defects of these instruments.On this basis,the writer develops a kind of gradual change throttleable cushion and with the theory of hydromechanics,make the theoretical analysis of them.
