Detection of the two-dimension(2D) acceleration signals plays an important role in bearing condition monitoring and fault diagnosis.A new structure of strain 2D acceleration sensor is proposed
which uses the cylindrical uniform cross section beam as the elastic element and based on 2D strain measurement method.The influence of structural parameters on the sensitivity and natural frequency of the sensor is analyzed based on the acceleration equation
and the dynamic response and the measurement precision of the sensor are analyzed by finite element method(FEM).The results show the proposed sensor has high precision
low frequency characteristics.Also it benefits a lot from its characteristics of uncoupling between the dimensions
low cost
easy to manufacture and assemble.
