Small deviations and big failures in vibration and noise isolation

摘要

The difference between design intent and actual implementation is frequently a problem inrnreal constructions. For vibration and noise isolation hardware, seemingly innocuousrndeviations can result in major deficiencies in performance. From hardware selection torninstallation and adjustment, vibration isolation systems present significant challenges. Inrnthis paper, we offer insight into a broad spectrum of problematic rotating mechanicalrnsystems. Numerous categories of vibration-isolation failure are identified, and detailedrnphotographs highlight subtle errors in isolator selection, installation, and adjustment thatrncan lead to poor vibration and noise performance. A spectacular example ofrncomprehensive facility-wide failure is given, with ground vibration data from a brownfieldrninfill site adjacent to an outdated textile factory.
