液压缸缓冲装置有节流式与卸压式两种。对于缓冲装置的要求是:缓冲压力峰值低、噪声小、速度衰减平缓、行程定位精度高、缓冲时间短,能达到基本上完全缓冲。缓冲过程是动态过程,通过理论分析,导出精确的结果是很困难的。然而,可对过程进行简化,找到基本规律,从而指导设计。一、各种节流缓冲的比较节流缓冲装置如图1所示,缓冲过程的运动微分方程式如下。 Cylinder cushioning devices are throttled and pressure relief type two. The requirements for the buffer device are: low peak buffer pressure, low noise, slow speed attenuation, high positioning accuracy, short buffer time, to achieve a substantially complete buffer. The buffering process is a dynamic process. Through theoretical analysis, it is very difficult to derive accurate results. However, the process can be simplified to find the basic rules to guide the design. A comparison of various throttling buffer Throttling buffer device shown in Figure 1, the damping process of differential equations as follows.
