Abstract	Using the finite element method, according to the actual size, building an entity model, the finite element simulation was conducted by a series of procedures, such as meshing, applying loads and solving. Then the temperature field and flow field with the three wires structure in the sensitive element were calculated in different tilting states. The results show that a heated hotwire forms definite temperature field and flow field in the sensitive element. When it is gradient, the two fields distribute no longer symmetrically. In the level state, the airflow velocity at the two hotwires is equal, so the resistance of both detection hotwires are also equal, then the output of the bridge circuit is zero; In the incline state, the airflow velocity difference at the two hotwires will change with the tilt angle, so it lead to change with the resistance difference of both two hotwires, then the bridge outputs a voltage signal with corresponding to the tilt angle. This analysis method provides a beneficial attempt for the practical research of the gas pendulum tilt sensor.
