| 英文摘要: |
| Electromechanical dynamics analysis and simulation on a rollforming equipment with both sides variable cross-section are discussed in this study. The system includes mechanical parts and electromagnetism parts, and it is a strongly coupled electromechanical system. Based on a virtual work principle and given power，generalized forces of this system are obtained. By using Lagrange-Maxwell equations, a model of electromechanical dynamics is established. Differential equations of two-phase winding on d-q axis are obtained by Park transformation, which comes from three-phase winding equations on the A-B-C axis. This system is solved with the 4th order Runge-Kutta’s method, and discrete solutions of all variables are obtained. Finally, by using Matlab language, the system is simulated. The results show that the proposed method works very well. |
