本文向读者介绍电液伺服试验机上控制方式转换的一种新方法。采用这种方法除了能实现装卸试样的转换以外,还可以实现不卸试样下试验过程中控制方式的转换,除了允许在静态时实现转换以外,还可以实现动态时的转换。作者从设计思想、工作原理、动态分析和操作步骤等方面作了较细的叙述。图3张。 This article introduces the reader to a new method of electro-hydraulic servo test machine control mode conversion. In addition to this method can be achieved in addition to the conversion of loading and unloading samples, but also can be achieved under the control of the sample test process conversion, in addition to allowing the conversion in the static, but also can achieve dynamic conversion. The author made a detailed narration from the aspects of design thought, working principle, dynamic analysis and operation steps. Figure 3 Zhang.
