Summary: | The article describes the particulars of transferring the dynamic process applying the spring and explains the possibilities of diagnostics for support bearings insulated from the external body using resilient elements. The carried out research has revealed methodology for investigation and suggested a suitable research stand. The input signal of impulse type was submitted to the system to observe free oscillations in the stand. Also, the system was stimulated employing an electromagnetic vibrator to research the transfer function of the spring. Finally, using output and input signals at the ends of the spring, the transfer function was derived.

Dinaminio proceso perdavimo spyruokle tyrimas
Santrauka
Straipsnyje nagrinėjami dinaminio proceso perdavimo spyruokle ypatumai bei galimybės ir kaip tai panaudoti spyruoklėmis vibroizoliuotų atramų diagnostikai. Buvo sukurta tyrimo metodika ir atitinkamas matavimo stendas spyruoklės įėjimo ir išėjimo charakteristikoms gauti. Naudojant impulsinio tipo signalą, gautas sistemos savųjų virpesių spektras, taip pat sistema žadinta vibratoriumi, siekiant ištirti ir įvertinti spyruoklės perdavimo funkciją esant nerezonansiniams dažniams. Analizuojant išmatuotas realizacijas, išvesta perdavimo funkcija.
Reikšminiai žodžiai: perdavimo funkcija, slopinimo koeficientas, spyruoklė, diagnostika, dažninė charakteristika.
