N2 - A new analytical model of Scratch Drive Actuator (SDA) is proposed in this paper, which considers its deforming states and geometry characteristics. This model contains three kinds of conditions: low driving voltage, critical driving voltage and high driving voltage. The storing strain energy in the SDA is studied under different conditions because the working performance of the SDA mainly depends on it. It is shown that a good agreement between theoretical results and experimental values is achieved with respect to the critical working voltage, which verifies the validity of the new model. Furthermore, analysis results demonstrate that it is necessary to choose appropriate design parameters of the SDA so that the SDA works near the critical state. Finally, discussions and suggestions for the design of SDA are presented in this paper. It is shown that the model and simulations can be used as design tools to optimize the design parameters of the SDA and to improve the dynamic performance of the SDA.
