| Abstract: |
| Based on the basic principles of electricity and dynamics,this thesis builds and analyses a linear vibration model which is a fairly complex system because the electricity and dynamics are interactive in it.By the special structure of the model which is similar to a coil loudspeaker,the authors make a clear distinction between two magnetic fields-induced and original ones and point out that they are perpendicular and independent with each other,meanwhile the relationships between electrical and dynamics coordinate axis are specified with.This model should to get the convergent solution of a third-order positive coefficient homogeneous differential equation at first,and then the complete solution that includes both the transient state term and steady state term.Moreover,in view of work and energy,this thesis,demonstrates the correctness of the model by judging the phase difference between voltage and electric current,and presents a means of demonstration to the similar models. |
