| 摘 要： | 利用ANSYS-FLOTRAN CFD软件,采用有限元方法,通过建立气流式水平姿态传感器敏感元件的三维实体模型、划分网格、加载和求解等途径,进行了有限元仿真,计算了敏感元件内部的流场,并采用了按实际尺寸比例大小建立整体模型的方法。结果表明：三维实体建模与二位平面建模相比较,这种全尺寸的三维实体建模方法可以使得计算结果更加全面准确,为气流式水平姿态传感器的实用化研究提供更加可靠完备的理论依据。

| Abstract: | Using ANSYS-FLOTRAN CFD program,the finite element simulation is conducted by a series of procedures,such as three-dimensional model building of airflow level posture sensor,network modifying,loads applying and equation solving.The flow field caused by the two heat in three-dimensional hermetic chamber of sensitive element of airflow level posture sensor is calculated,FEM analysis has been obtained,The numerical results show that compared with two-dimensional modeling,the simulation result of three-dimensional modeling are more comprehensive and accurate,which provides more reliable basis for practical research of the airflow level posture sensor. |
