N2 - A vibration wire strain sensor based on photoelectric detection is designed. The sensor uses one coil to excite the vibrating wire and a photoelectric sensor to pick up the vibration of vibrating wire. And it's verified by experiments. Moreover, the device to fix the vibrating wire is optimized, making it closer to the model of Double-Clamped. The mathematical model of the vibration wire with the damping effect is established, and the simulation is carried out by ANSYS. The experimental results, theoretical calculation and simulation results have preferably coherence. The accuracy of the way to process the signal reaches 2 με.
