| Abstract: | Describes the principle of the touch mode capacitive pressure sensor.Based on the FEA method,provide an ANSYS program,which can analyse some nonlinearity problems such as contact,large deflection and so on when the diaphragm is under pressure load.And the program can be used to get the relationship between capacitance and pressure directly.Compared the measured and other simulation results,the feasibility of the ANSYS applied to analyse the nonlinearity about the touch mode capacitive pressure sensor is validated.And it manifests the practicability of this ANSYS method. |
