YD—1型打桩机液压系统的特性分析

Characteristic analysis of hydraulic system for Model YD-1 pile-driver

本文采用阻力特性分析法建立了YD-1型打桩机内差动液压系统油缸的运动方程,分析了系统参数对油缸冲击速度及加速度的影响。

Using a method on analysing resistance of hydraulic system, this paper establishes the moving equation of cylinder in the inner differential system of Model YD-1 Hydraulic Pile-drier and analysis how the system parameter affects the stroking speed and acceleration of cylinder.
