Adequacy of Mathematical and Physical Model of Oscillating Mechatronic Device
Mostly used mechatronic devices are electrical energy converters into mechanical energy. Because of this reason it is very important to research them. One of the research types are mathematical mechatronic drive models. The research of drive was concluded using three methods: performing a physical experiment, performing a mathematical model, electromagnetic force, winding‘s inductivity solutions by calculating (2), (3), (4) dependence and performing mathematical model when the values are approximate from previously calculated dependency surfaces. The voltage of the energy source that was feeding the drive was changed and monitoring of motor moving part’s oscillating amplitude and force in the circuit. During the mathematical model, using finite elements method, the results are closer to the physical model than mathematical model, when electromagnetic force is calculated taking the first degree of the order function. Because of that reason mathematical model, using finite elements method is acceptable. It is worth to explore finite elements method usage in mathematical model.
