拉力试验机位移系统故障的处理

Tensile testing machine displacement system fault processing

*、首先检查拉力机位移传感器。由于拉力机位移系统采用的是三闭环控制方式；所以应该先断开位移系统中的回路，使其成为开环系统。然后测量位移传感器的反馈值，重复几次以后，测量到的传感器反馈数据为一个线性变化的直线，判定传感器是否正常。

The first plane reservation, first check the tension sensor. Due to the tension of reservation moving system adopts three closed loop control mode; So should first disconnect displacement circuit in the system, make the open loop system. Then measured displacement sensor feedback value, after a few repetitions, the measured sensor data as a linear change of straight line, determine whether the sensor is normal.

第二、接着检查放大器单元。如果位移传感器没有问题，应该重点检查拉力机放大器单元，正常的放大器单元的输出信号应该成线性变化趋势。

The second, and then check the amplifier unit. If there is no problem, the displacement sensor should be focusing on tensile machine amplifier unit, normal output signal amplifier unit should be a linear trend.

第三、如果不是上述原因引起的故障，则应检查电脑软件设定是否正确；或者重新标定和校正位移系统。

Third, if not the causes of failure, you should check the set of computer software is correct; Or displacement of calibration and correction system.
