Peripherally restraining type rubber bearing

Die Angewandte Makromolekulare Chemie, 1996
AbstractSeismic isolation was reconfirmed to be extremely efficient for the protection of buildings, and hence human life, on the occasion of the Great Hanshin Earthquake. Rubber bearings are placed under the buildings for isolation, and thus the type of rubber bearings is a dominant factor for efficient isolation.

New UHMWPE/Rubber Bearing Alloy

Journal of Tribology, 1999
A new polymer bearing alloy has been developed that overcomes the high wear nonhydrodynamic deficiencies of UHMWPE when water-lubricated and the shaft wear and high breakaway friction of rubber bearings (Orndorff, Jr., R. L., 1988, “Thermoplastic-Rubber Polymer Alloys and Method for Producing the Same,” United States Patents, 4,725,151 and 4,735,982 ...

Experimental Investigations on Laminated Rubber Bearings

Bulletin of Earthquake Engineering, 2005
Increasing application of base isolation as a seismic protection method has subsequently increased its analytical and experimental studies. Being the most critical part of the base isolated buildings, accurate evaluation of structural properties and precise modeling of isolation devices is of utmost importance in predicting the response of the ...

An Investigation of Adaptive Rubber Bearings

Volume 8: Seismic Engineering, 2016
Proposed in this study are several innovative seismic isolators composed of rubber materials that are called adaptive rubber bearings based on their adaptive characteristics. The materials used in the proposed isolators are free of lead commonly found in lead rubber bearings.

Shape optimization of a rubber bearing

International Journal of Fatigue, 1991
Abstract Large deformations in a rubber bearing between two conical tubes may lead to squashing folds that can cause local rupture of the rubber followed by complete destruction of the bearing. A new method, CAO (computer-aided optimization), which is based on the simulation of biological growth, is used to avoid these squashing folds by reducing the

Extraction and Characterization of Latex and Natural Rubber from Rubber-Bearing Plants

Journal of Agricultural and Food Chemistry, 2010
Consecutive extraction of latex and natural rubber from the roots of rubber-bearing plants such as Taraxacum kok-saghyz (TKS), Scorzonera tau-saghyz (STS), and Scorzonera Uzbekistanica (SU) were carried out. Latex extraction was carried via two methods: Blender method and Flow method. The results of latex extraction were compared.

Coenzyme A and Aldolase in Rubber-bearing Plants

Nature, 1958
THERE is evidence that the biosynthesis of rubber from carbon dioxide and water in Parthenium argentatum 1 may proceed through acetate and β-methylcrotonate, and that acetate can also act as a precursor of rubber in Hevea brasiliensis 2. Co-enzyme A probably plays a vital part in the process.

Ageing Behaviour of Natural Rubber and High Damping Rubber Materials Used in Bridge Rubber Bearings

Advances in Structural Engineering, 2010
This paper attempts to reveal the ageing behaviour of natural rubber (NR) and high damping rubber (HDR) materials used in bridge rubber bearings. Using various degradation factors such as thermal oxidation, ultraviolet, ozone, low temperature ozone, salt water and acid rain, a series of environmental accelerated ageing tests were conducted to ...

Nonlinear natural rubber bearings for seismic isolation

Nuclear Engineering and Design, 1985
Abstract This paper summarizes the results of a ten-year joint research program on base isolation carried out by the Malaysian Rubber Producers' Research Association in England and the University of California at Berkeley. Special rubber bearings have been developed which protect buildings and their contents from earthquake damage without requiring ...
