Numerical Modeling of Microwave-Photonic Sensor System for Load Sensing Bearings

摘要

The work presents results of numerical modeling of the microwave-photonic sensor system for automotive load sensing bearings. The system is designed for strain measurement of the hub bearing outer ring. The system comprises three fiber-optic sensors based on the addressed fiber Bragg structures (AFBS) with two symmetrical phase shifts. Two structures are used as strain sensors, while the third sensor is used for temperature compensation. The results confirm the high accuracy of AFBS central wavelength determination using the microwave-photonic interrogation approach, which makes it suitable for application in load sensing bearings for vehicle dynamics control.
