Abstract To suppress the significant vibration line spectra of piping systems under multi-frequency harmonic excitations. a novel dynamic vibration absorber (NDVA) is designed. The NDVA integrates numerous independent resonant units within a finite space through an ingenious structural design and possesses rich frequency regulation characteristics. A vibration model of the piping syst... https://ashleyshomestores.shop/product-category/5-piece-king-upholstered-bedroom/
