摘要
参考有限元分析结果,对实桥进行缩尺和简化,模拟刚性铰及内部支座的实际工作环境,进行刚性铰模型试验.实验表明在受力复杂的工作环境下,聚四氟乙烯材料滑板的耐磨性稍优于超高分子量聚乙烯滑板支座,带球铰的滑板支座优于不带球铰的滑板支座.设置调节支座间隙的装置、增大滑板接触面的面积,可提高支座耐磨性,改善刚性铰的运动工作性能.
Based on finite element analysis, a model is established according to the scale -down and simplified bridge. It is then tested by simulating the actual working environment of internal abutment in rigid - hinge. It is shown through the experimental results that the abrasion resisting properties of PTFE is slightly better than that of UHMW- PE in the complicated working conditions. Sliding plate bearing support with spherical hinge is better than the＇one without it. The setting of support gap actuating device and enlarging sliding - plate contact area are beneficial to enhance abrasion resisting properties of support and to improve the dynamic performance of rigid - hinge.
