Equivalent electromechanical circuits for modelling of dynamic systems

This thesis deals with solving and modelling of dynamical systems using electromechanical analogy. A review of the use of electromechanical analogy of systems is made. Then a mechanical model of a piezoelectric beam is described by using differential equations and subsequently an equivalent circuit is made by using a voltage analogy, in which the power is simulated. A mechanical model and its equivalent circuit are made for the electromagnetic vibration generator using current analogy. The last part of the work is the modelling of complex piezoelectric and electromagnetic models and the influence of body weights on the vibrations
