摘　　要：The fast electromagnetic drive mechanism based on fast switch shows extensive applications in many areas,but there is still a lack of unified evaluation parameters as to evaluate the dynamic characteristics due to diversity and complexity of the mechanisms.Three interrelated evaluation parameters are presented for topology analysis,namely the electromagnetic force sensitivity coefficient,the initial time constant and the sensitivity contribution coefficient.The specific parameters based on evaluation can provide a basis for structural performance assessment as well as topology optimization.Comparison between the dynamic parameters of the discoid repulsion mechanism and the solenoid thrust mechanism shows that,the discoid one is superior to the solenoid one.The proposed research is to establish a general methodology for topology analysis and optimization of the electromagnetic mechanisms.The fast electromagnetic drive mechanism based on fast switch shows extensive applications in many areas, but there is still a lack of unified evaluation parameters as to evaluate the dynamic characteristics due to diversity and complexity of the mechanisms.
