Impact system excited by a source of limited power
Original language description
Electromechanical system with one degree of freedom in mechanical oscillating part and other degrees in rotation a electrical subsystems is investigated by means of numerical solution of derived equations in dimensionless form. The most important nonlinearities are impacts of the main body on the stiff but deformable stop. Other nonlinear effects are introduced into system by the force transformation from unbalance exciter with limited power into the oscillating subsystem and also by nonlinear magneticflux in the driving electromotor. Presented numerical simulation was focused on the study of the influence of exciting unbalance level on the time histories of caused oscillations and of phase trajectories. The various responses were shown and discussedin examples.

Systém s rázy buzený zdrojem omezeného výkonu
Czech description
Numerickým řešením pohybových rovnic v bezrozměrovém tvaru byl zkoumán elektromagnetický systém obsahující mechanickou podsoustavu s jedním stupněm volnosti. Jsou uvažovány nelinearity v elektrickém obvodu, v mechanické podsoustavě (rázy) a ve vazbě mezikmitající hmotou a vibrátorem konečného výkonu. Na příkladech je ukázán vliv rázu a velikosti buzení.
