Abstract

Aiming at problems in bearing vibration monitoring

a 3D mechanical differential piezoelectric acceleration sensor is proposed to be applied in bearing vibration monitoring and fault diagnosis based on single inertial mass.Mass-spring-damper dynamic model of the sensor is built and performance indexes and dynamic response curves are obtained.Meanwhile

the model is simulated with FEM

the simulation results show that the 3D mechanical differential piezoelectric acceleration sensor is able to acquire the bearing vibration signal with high natural frequency and high output sensitivity and wide measurement frequency range.Meanwhile

it has advantages of simple structure and small sizes.
