Abstract

The NB fan is placed in the center of the seismic platform. The commercial DVD pick-up head is used as the sensor to measure the vibration of the NB fan. We use the automatic positioning program to control the micro stage, and let the DVD displacement sensor to position the zero-point of S-curve automatically. Experimental results indicate that the standard deviation is less than 5%, which indicates that the displacement senor has an excellent stabilization. Furthermore, the commercial DVD pick-up head is used as the sensor, so this system not only reduces the cost but also obtains good vibration measurement results.
