Vertical stiffness and deformation analysis models of rubber isolators in compression and compression-shear states / W. G. Liu in Journal of engineering mechanics, Vol. 135 N° 9 (Septembre 2009) 

Public ISBD [article]  in Journal of engineering mechanics > Vol. 135 N° 9 (Septembre 2009) . - pp. 945-952 Titre : Vertical stiffness and deformation analysis models of rubber isolators in compression and compression-shear states Type de document : texte imprimé Auteurs : W. G. Liu, Auteur ; He, W. F., Auteur ; Feng, D. M., Auteur Article en page(s) : pp. 945-952 Note générale : Mécanique appliquée Langues : Anglais (eng) Mots-clés : Rubbe  Isolation  Stiffness  Deformation  Analytical  techniques  Compression. Résumé : The vertical stiffness and deformation theories of rubber isolators in compression and compression-shear states are systemically researched in the paper, a series of basic concepts, such as origin compression stiffness, origin compression longitudinal elastic modulus, offset vertical stiffness, etc. are suggested with corresponding theoretical formula and experimental estimation method. Based on the basic concepts and newly suggested calculating theories, the deformation calculating theory related to pure compression state and compression-shear state of isolating bearing is established. The vertical stiffness, offset vertical stiffness and deformation tests are performed with nature rubber bearings and lead plug rubber bearings total 16 original specimens to verify the new concepts and computation model of rubber isolators. All test results show that the theories established in the paper are suitable for analyzing the vertical stiffness and deformation of rubber isolators.
