Passive Multi-Layer Composite Damper of Flat Belt Tensioner Idler
Source abstract
Abstract
In this study, the effect of multi-layer composite passive dampers on the dynamic properties of a mechanical system (a testing machine tool bench) was tested. Passive dampers are characterized by a layered structure, with each layer consisting of a specific structure of different materials, preferably foam polymers. The dynamic excitation is caused by a flat belt driving the rotor roller bearing by direct contact of the flat belt and bearing pin at a frequency of 1170–2170 Hz. The dynamic effects of the flat belt directly affect the complex dynamic effects inside rotor bearing, mainly torsional vibrations. A significant modification in the amplitude and frequency modulation and other evaluated dynamic parameters was obtained. By implementing passive dampers and modifying the mass and material damping, a decrease in amplitude at resonance of almost 30% was achieved.
