| 1、首先对位移传感器进行检查，因为拉力试验机系统是一个闭环系统，要想知道是哪个部分出现了问题，就一定要切断系统中的回路，使其成为一个开环的系统。从而可以判断试验机的传感器信号是不是正常。这个时候也要断开位移传感器的反馈信号，使其成为开环。此时工作站发出一个控制动作器移动的信号，对传感器的反馈值进行测量，在几次重复之后，传感器的反馈数据值可以组成一条直线，这个直线是线性变化的，从而就可以知道传感器是不是有问题了。 1, first check the displacement sensor, because the system of tensile testing machine is a closed system, want to know which part of the problem, we must cut off the system in the loop, make it become an open loop system. Thus, the sensor signal of the test machine can be judged to be normal. At this time, the feedback signal of the displacement sensor is disconnected so that it becomes open-loop. The workstation sends a control signal to move the actuator, sensors to measure the value of the feedback, after several repetitions, the sensor feedback data values can be composed of a straight line, the line is a linear change, so you can know sensor is not a problem. 2、 其次就是对拉力试验机的放大器单元的检查，在已经排除了位移传感器的问题之后，因为拉力试验机的系统是一个闭环系统，放大器单元的正常与否是一定要进行检查的，方法就是断开放大器单元的输出信号。将输出接线拆除，在放大器单元加上一个直流输入信号，然后测量摆锤冲击试验机放大器单元的输出情况，在重复试验几次之后，得到一个放大器单元输出信号的线性变化趋势数据，这样就可以知道放大器单元是不是有问题了。 2, the second is the check amplifier unit on the tensile testing machine, after the displacement sensor problem has been ruled out, because the system of tensile testing machine is a closed system, the amplifier unit is normal or not is to check the method is to disconnect the output signal amplification unit. The output terminal removal, DC input signal in the amplifier unit with an output, and then measuring the pendulum impact testing machine amplifier unit, after several repeated trials, data from the linear trend of the output signal of an amplifier unit, so that you can know the amplifier unit is not a problem. |
