| Abstract: | The magnetically controlled shape memory alloy is a new type of shape memory alloy,which has large shape variation,fast dynamic response,high power density and high efficiency of electromechaical energy conversion in the magnetic field.In this paper,a novel linear actuator and the scheme of controlling system are proposed.Based on the analysis of the system,the dynamic model is established.With the analysis and calculation of the model,the MSMA actuator prototype and the experimental results are given.The results show the validity and practicability of the model.The research in this paper provides the theoretic and experimental basis for the application of MSMA in intelligent systems. |
