Paper Title:
Analysis on Mechanism of Effect of Acceleration Sensor by Three-Dimensional Finite Element Method
  Abstract

The mechanism of effect of the acceleration on acceleration sensor is preliminary elucidated. Using the three-dimensional finite element method, the temperature field in sensing element of the sensor under the effect of the different acceleration have been obtained by a series of procedure , such as model building ,meshing ,loads applying and equation solving. In the process ANSYS2FLOTRAN CFD program is applied. By the numerical results and experiments, the effect of input acceleration on accleration sensor is analogous to the effect of input tilt angle on the sensor, which also will change the temperature of gas flow at two thermal resistors ,so lead to change of the current difference of both thermistor wires, finally the bridge outputs a voltage signal corresponding to the acceleration.
