大家好，今天给大家介绍这一款柔性转子实验台，它的型号是FRT-1000。这款实验台有三种规格，这是单跨转子，这双跨转子，这是三跨转子，根据转轴的数量，及安装的滑动轴承的数量来区别的。

它的主要功能是可以开展柔性转子的动平衡模拟、启停机测试、轴心轨迹测量、轴心位置测量、波德图、瀑布图、还可以测量转子的临界转速、共振测试。

这个是和它配合使用的一个控制器，控制器可以显示转速，正反转切换、暂停运行切换、转速调节、电机运行的转速范围是0-10000rpm，还有一些其他的配件，如油膜涡动的轴承座，可以开展油膜涡动及油膜震荡试验，这是油膜涡动的配套的柔性轴，转子盘卡套锁紧的特殊扳手，内六角扳手、配重螺栓、控制箱保险丝、联轴器、紧固螺栓所组成。

现在我们启动实验台给大家演示下，这个实验台可以配置的传感器类型有压电式ICP加速度振动传感器，非接触式电涡流位移传感器、这常用的种类的传感器。

把电缆插头插到插座上后，打开红色的电源开关，这时候控制器上的仪表就会有显示，就会显示当前的转速，首先按下运行按钮，手动旋转转速调节旋钮，电机此时就会启动，此时电机转速发聩在转速表上。我们逐渐的调高转速，三跨转子的临界转速在5000pm附近，随着转速的上升，我们明显能够感受到振动的加剧，过了临界转速后，振动和噪声反而逐渐减小， 现在我们将转速减小，让它再过一次临界转速，随着转速的下降，振动和噪声逐渐加剧，当实验台运行在一阶临界转速下，振动很小，噪声也很小，运行平顺。

如果我们把试验运行在目标转速后，然后按下停止按钮，此时实验台会自动停机，然后再按下，它就会运行到目标转速、就可以开展实验台启停机实验。

Hello everyone, today I will introduce this flexible rotor experimental platform, which is model FRT-1000. This experimental bench has three specifications: single span rotor, double span rotor, and triple span rotor, which are distinguished based on the number of shafts and the number of sliding bearings installed.

Its main function is to conduct dynamic balance simulation of flexible rotors, start stop testing, axis trajectory measurement, axis position measurement, Bode plot, waterfall plot, as well as critical speed and resonance testing of rotors.

This is a controller used in conjunction with it. The controller can display the speed, switch between forward and reverse rotation, pause operation, adjust the speed, and the speed range of the motor is 0-10000rpm. There are also some other accessories, such as the bearing seat for oil film vortex, which can conduct oil film vortex and oil film oscillation tests. This is a flexible shaft that matches the oil film vortex, a special wrench for locking the rotor disc sleeve, an Allen wrench, a counterweight bolt, a control box fuse, a coupling, and fastening bolts.

Now let's start the experimental platform to demonstrate to everyone. The types of sensors that can be configured on this platform include piezoelectric ICP acceleration vibration sensors, non-contact eddy current displacement sensors, and commonly used types of sensors.

After inserting the cable plug into the socket, turn on the red power switch. At this time, the instrument on the controller will display the current speed. First, press the run button and manually rotate the speed adjustment knob. The motor will start at this time, and the motor speed will sound on the tachometer. We gradually increased the speed, and the critical speed of the three span rotor was around 5000pm. As the speed increased, we could clearly feel the intensification of vibration. After passing the critical speed, the vibration and noise gradually decreased. Now we reduce the speed and let it pass the critical speed again. As the speed decreases, the vibration and noise gradually intensify. When the experimental bench runs at the first critical speed, the vibration and noise are very small, and the operation is smooth.

If we run the experiment at the target speed and then press the stop button, the test bench will automatically stop. Then press it again, it will run to the target speed, and the test bench start stop experiment can be carried out.
