【Abstract】 The basic structure and control system of electromagnetic launcher for forest fire control were figured out,and then its mathematical model was built up. Finally,the launcher’s model was simulated and analyzed by a software Maxwell2D,which was used for the finite element analysis(FEA). The results showed that the model had a good dynamic performance in the conditions of given structural parameters and control system. In the process of analysis,the effects of the lateral force caused by moving part on the whole structure and the demagnetization of permanent-magnet were also explored in this study.更多还原
