06 The simulation and analysis on permanent magnetism actuator dynamic characteristics considering ambient temperatures ZHANG Qing- jie, YUAN Hai- wen, LIU Ying- yi ( School of Automation Science and Electrical Engineering,Beihang University,Beijing 100191,China) Abstract: Aimed at impact on dynamic characteristics of permanent magnetic actuator as ambient temper- ature change,the paper establishes the dynamic characteristics mathematical models in two movement stages of permanent magnetic actuator considering ambient temperature impact. Based on the models,the paper analysed the static characteristics parameters considering ambient temperature and the temperature characteristics of control capacitor value and coil resistance. And the dynamic characteristics of perma- nent magnetic actuator taking the temperature into account were obtained in the paper. Experimental re- sults show that in working temperature range,switching time dispersion is bigger and the dynamic charac- teristics calculation results of permanent magnetic actuator considering ambient temperature implications are closer to experimental test results. The temperature impact levels of permanent magnetic actuator characteristics parameters are different when the temperature changes after the curves are analyzed. And the largest temperature impact level is magnet performance parameters,followed by capacitor capaci- tance,and finally the coil resistance. The characteristics analysis method taking the influence of tempera- ture into account will provide synchronous switching control and permanent magnetic actuator optimization design with theoretical guidance and basis.
