Rubber versus steel vibration isolators - The audible frequency contest
2005 (English)In: KGK Kautschuk Gummi Kunststoffe, ISSN 0948-3276, Vol. 58, no 11, 564-569 p.Article in journal (Refereed) Published
The audible frequency axial dynamic stiffness of three vibration isolators plausibly used in the design of a ship main engine suspension system are examined and compared for different static preloads. An indirect measurement method is used to investigate the blocked dynamic transfer stiffness using a specially designed test rig displaying a strong frequency dependence where resonance and antiresonance phenomena appear in the form of troughs and peaks respectively. The significant influence of the preload effects is also assessed for each isolator. Clearly, the rubber isolator presents superior performances in comparison with the two others, steel and combined steel-rubber isolators, over the studied frequency range 200 to 1000 Hz for each preload 30, 40 and 50 kN.
