1、采用计算机监督控制系统，提供可靠、稳定的系统控制，以及完备、高效、稳定的系统保护。（包括对功放电流的监测保护）； 2、完全计算机控制，提供良好的操作界面，简单、直观的操作，指导操作人员有步骤的正确操作； 3、标定系统，指导操作人员正确完成系统的标定工作； 4、对加速度实行闭环控制，使载荷非常稳定，波动小于1.5%； 5、指令频率能自动跟随机械系统固有频率变化，使系统始终工作于共振状态； 6、自动化程度高，系统在发生下列情况之一时能可靠地停止试验: 试件上出现一定长度的裂纹； 完成预定的循环数； 载荷幅度超过(或低于)预置的上限(下限)。

1, the computer supervision and control system is adopted to provide reliable and stable system control, as well as complete, efficient and stable system protection. (including the monitoring and protection of power amplifier current); 2, completely control computer, to provide a good user interface, simple and intuitive operation, correct operation guides steps; 3, calibration system guides correct calibration system; 4, the implementation of acceleration closed-loop control, the load is very stable 5, fluctuation is less than 1.5%; and instruction frequency can automatically follow the natural frequency of the mechanical system changes, so that the system can work in resonance state; 6, a high degree of automation, the system can reliably stop the test in one of the following conditions: try to crack certain length pieces; complete the cycle number of predetermined amplitude (more than load; or below the preset upper (lower)).
