Original abstract
This contribution deals with the computational modelling of nonlinear rotor dynamic systems. The theoretical base of the method of dynamic compliances and modal method, completed by the method of trigonometric collocation, are presented. The main aim of analysis is focused on the solutions of the eigenvalue problem, steady – state and transient responses. The algorithms for the solution of this range the problems are presented. The finite element method, method of dynamic compliances and modal method are supplemented by the trigonometric collocation method. The theoretical analysis is supplemented using the solution of the model task, which is focused on the application of the trigonometric collocation method. The solution of a technical application, which is a pump, is presented in this contribution
Czech abstract
Příspěvek se zabývá výpočtovým modelováním dynamických vlastností nelineárních rotorových soustav. Jsou uvedeny teoretické základy metody dynamických poddajností a modální metody. Vlastní analýza je zaměřena na řešení problému vlastních hodnot, řešení odezvy při vynuceném ustáleném a přechodovém kmitání. Jsou uvedeny algoritmy pro řešení uvedeného okruhu úloh. Metoda konečných prvků a metoda dynamických poddajností jsou doplněny o metodu trigonometrických kolokací. Teoretická analýza bude doplněna řešením modelové úlohy, která je zaměřena zejména na metodu trigonometrických kolokací. Dále bude v příspěvku ve zkratce uvedeno řešení úlohy technické praxe, kterým je čerpadlo.
