橡胶支座中橡胶板基于抗压弹性模量的寿命预测

橡胶板是橡胶支座的重要组成部分，对橡胶支座以及建筑物整体结构的稳定起着重要的作用。对橡胶板的使用寿命做出预测，提出更换周期，有助于工程做好更换计划。以抗压弹性模量对橡胶支座中占绝大部分的橡胶板分别作80℃，90℃以及100℃的加快老化试验。结果表明，在不考虑其它因素下通过阿伦尼乌斯方程拟合推导出橡胶板在年平均温度为23℃下的使用寿命在37．60 a之间。

Service Life Prediction for Bubber Tile of Rubber Bearing Based on Compressive Elastic Modulus

Rubber tile is one of the most important parts in rubber bearing, which plays a key role on stabilizing the rubber bearing and hydraulic architecture.It is conductive to replace in bulk on schedule in the engineering by the service life prediction and re-placement cycle for rubber tile.In this article, aging experiment on rubber tile is respectively carried out in 70℃、 90℃、 100℃tested by compressive elastic modulus.It concludes that the average service life of rubber tile is 37.60 years in 23℃by fitting the Arrhenius empiric equation without consideration for the other influencing factors.
