Since the overloads of the electromagnetic flame-proof mechanism under different working conditions are complex and hard to be verified,a numerical simulation method of this mechanism working process is proposed with the combination of Adams and Simulink.First,a simulation model of electromagnetic flame-proof mechanism was established,which includes the safety pin,the spring,and the exciting coils and so on.Then,the model was imported to Adams taking constraints into consideration,which include the contacts,kinematic pairs and the spring.The co-simulation model was established through the union of Adams and Simulink.The model was tested via simulations,and the obtained results were analyzed finally.The results show that the method can simulate the dynamic process of the electromagnetic flame-proof mechanism during the service process and under the normal power supply condition,and therefore the motion displacements of the electromagnetic pin under different working conditions can be obtained through simulations.It can verify the mechanism's designing rationality,thus laying the foundation for the physical prototype testing and reducing the repetition of the product's design process. 展开更多
