Nonlinear rotation and shear stiffness theory and experiment research on rubber isolators / W. F. He in Journal of engineering mechanics, Vol. 138 N° 5 (Mai 2012) 

Public ISBD [article]  in Journal of engineering mechanics > Vol. 138 N° 5 (Mai 2012) . - pp.441-449 Titre : Nonlinear rotation and shear stiffness theory and experiment research on rubber isolators Type de document : texte imprimé Auteurs : W. F. He, Auteur ; W. G. Liu, Auteur ; Q. R. Yang, Auteur Année de publication : 2012 Article en page(s) : pp.441-449 Note générale : Mécanique appliquée Langues : Anglais (eng) Mots-clés : Rubber  isolators  Shear  stiffness  Rotation  stiffness Résumé : The rotation and shear property theory of rubber bearings is researched in the paper. On the basis of the nonlinear rotational stiffness and Haringx elastomer model, a simple mechanics model is provided to analyze the rotation, compression, and shear property for rubber isolators. The rotational stiffness analysis theories corresponding to different shear deformation state are established on the basis of the properties of rubber material and isolators. The tests of natural rubber bearings (RB) and lead plug rubber bearings (LRB) were conducted to testify the nonlinear rotational stiffness analysis model and the shear hysteretic model proposed in the paper. The test results show that both nonlinear rotational stiffness analysis model and shear hysteretic model proposed in the paper could be used effectively to analyze the mechanics properties.
