This paper analyzes the principle and characteristic of damper.With the consideration of lid open process of rice cooker we use theoretical calculation to deduce a formula to compute the resistance of damper.Moreover,we establish a mechanical model of the resistance of damper by using ANSYS.Compared with the experimental data,it is proved that this model is reliable it can be used to compute the change of damper’s Torque related to the movement of the damper.This conclusion can be used in the design of dampers and in the rice cooker’s quality control process.
