摘要
对自行开发的多通道结构试验台的电液伺服系统组成、工作原理及液压元件应用上的特点进行了介绍和分析。该伺服系统可实现双作动头的同步或异步协调加载,并通过使用伺服比例阀及不同变量泵组合,实现了对试验力的连续控制,节约了能源。
The composition, operating principle of the new developed electrohydraulic servo system of muhichannel structure tester were introduced. The system can realize loading in synchronism or nonsynchronous coordination by two actuator-heads, can control test load continuously by proportional servo valve and the combination of different variable pumps, and energy is saved.
