摘要: 高阻尼橡胶支座因其独有的阻尼特性和环保优势受到日益广泛的关注和研究,国外研究机构关于高阻尼橡胶支座已有较为完善的研究成果。 为推动高阻尼橡胶支座在我国的研究和应用,亟需系统梳理和思考现有研究成果。 首先梳理了国内外高阻尼橡胶支座基本力学性能的研究脉络和情况,而后重点对高阻尼橡胶支座力学模型的相关研究进行了总结,讨论了现有速度无关性模型和速度相关型模型的优势与不足;总结了竖向压力相关性、剪切应变相关性和温度相关性对高阻尼橡胶支座力学性能的影响。 最后简述了高阻尼橡胶支座稳定性的研究现状。给出了高阻尼橡胶支座在复杂受力性能、极限荷载作用稳定、反复荷载作用疲劳等方向的相关研究建议。

Abstract: High damping rubber bearing (HDRB) has received more and more attention and research owing to its unique
damping characteristics and environmental protection advantages. Foreign research institutions have relatively complete
research results on HDRB. In order to promote the research and application of HDRB in China, it is urgent to systematically
review and consider the existing research results. Firstly, the research context and situation of the basic mechanical
properties of HDRB at home and abroad were reviewed. Then, the relevant research on the mechanical model of HDRB was
summarized, and the advantages and disadvantages of the model with rate⁃dependent and the model without rate⁃dependent
were discussed. The influence of the factors on mechanical properties of HDRB was summarized, including vertical pressure
dependence, shear strain dependence and temperature dependence. Finally, the research status of HDRB stability was
briefly described. The relevant research suggestions for HDRB in the directions of complex mechanical performance,
ultimate load stability, and repeated load fatigue were given.
