Random vibration testing of a quasi-zero-stiffness isolator for distribution transformers and the effects of composite damping parameters
To address low-frequency vibration and structure-borne sound transmission in distribution transformers, this study investigates a prototype quasi-zero-stiffness (QZS) low-frequency isolator with a composite particle damping unit. Broadband vertical random-vibration tests over 2-2000 Hz were conducted to evaluate the ef...
