XFY718为长征机床厂生产的大型三坐标液压仿形铣床。它具有价格低廉、工作可靠、操作简便等优点,对它的分析有利于了解其动态特性,发现不足及产生的原因,提出改良系统的方法,并进行最优参数组合,改善其动态性能同时也探讨了复兴液压技术手段。后部分对伺服阀——马达试验台进行了模型辨识,提出了一种简便、实用的辨识方法。
XFY718 is a large-scale three-coordinate hydraulic profile milling machine produced by Changzheng Machine Tool Works. It has the advantages of low price, reliable work, simple operation and so on. Its analysis is helpful to understand its dynamic characteristics, find out the causes and causes, put forward the method to improve the system, and optimize the combination of parameters to improve its dynamic performance Exploring the revival of hydraulic technology. The latter part of the servo valve - motor test bench model identification, proposed a simple and practical identification method.
