ANSYS modeling and calculation of micromachined airflow omnibearing level posture sensor

In this paper, the finite element modelling method of micromachined airflow omnibearing level posture sensor is presented. Through building the three-dimensional model of the sense organ, the finite element analysis of the sensor is carried out by using ANSYS software. The results show that: (1)Using the symmetry of the sense organ, a half-model is built first, which is convenient in modeling and observation of the results;(2) In the large grads of the fluid, a denser mesh can help save time and improve accuracy. This modelling method is of great significance on the precise research of micromachined airflow omnibearing level posture sensorpsilas sensitive mechanism.
