Three-Dimensional FEM Analysis of Effect of Acceleration on Airflow Level Posture Sensor
Using ANSYS-FLOTRAN CFD program, the finite element simulation is conducted by means of a series of procedures, such as three-dimensional model building of airflow level posture sensor, network modifying, loads applying equation solving, the flow field in three-dimensional hermetic chamber of sensitive element of airflow level posture sensor in different acceleration and inclination is Calculated, The numerical results show that for the sensor of airflow level posture sensor, the effect of acceleration and inclination is similar. Both of them can change the flow field of sensor, and will output a corresponding voltage. The simulation result of three-dimensional modeling is more comprehensive and accurate, which provides more reliable basis for practical research of the airflow level posture sensor.
