W pracy przedstawiono model naprężeń w paśmie blachy poddanej walcowaniu. Pozwala on efektywnie obliczać siłę oddziaływania pasma na walce robocze klatki, pulsację naprężeń osiowych w swobodnej części pasma oraz jego zastępczą sztywność poprzeczną w szczelnie. Pulsacja naprężeń może w pewnych warunkach wywołać parametryczne drgania pasma sterujące dopływem energii do klatki. Zjawisko to może być powodem...
The paper presents an approximate analysis based on a two models of the vibration of a mast supported by stay cables. The vibrations of the mast are excited by the separation of the Karman vortex street. It has been demonstrated that the vibration in the discussed structure has the self excited-parametric character. The paper includes tlie frequency and phase characteristics as well as the time plots...
