有限元仿真在某新型位移传感器标定中的应用

Application of Finite Element Analysis in Calibration of a New Type Displacement Sensor

针对非接触型磁力压电式位移传感器标定中存在的工作量大、误差因素多的问题,设计了通过有限元仿真进行标定的方法。采用ANSYS建立两磁体二维模型,定义材料属性后,划分有限元网格,模拟在空气介质下两磁体的作用力与位移关系曲线。通过实验对比验证了仿真结果的准确性。

Aiming at the problems of large workload and many error factors, in calibration of non-contactmagnetic piezoelectric type of displacement sensor, the method of calibration is designed by finite elementanalysis. Used ANSYS to sets up two-dimensional mode of the two magnets, defined the material properties anddivided the finite element mesh, than simulated the relationship between force and displacement of two magnetsin air medium. The accuracy of the simulation results is verified by experimental contrast.
