摘要
为了提高板式橡胶支座的抗横移性能,提高列车的行驶安全和桥梁的使用寿命,采用有限元方法,建立了板式橡胶支座的有限元模型,计算板式橡胶支座在荷载作用下的剪应力和剪应变,得到了板式橡胶支座横向和纵向抗剪弹性模量,并与试验结果进行了对比。计算结果表明,数值结果与试验结果吻合良好,为板式橡胶支座的优化设计提供了技术支持。
In order, to improve the capability of resisting lateral displacements of plate rubber support so as to ensure the train run safely and prolong the natural life of bridge, A FEM model of plate rubber support is established to calculate its shear stress and strain. The lateral and lengthways shear elastic modulus are obtained. The results of finite element method are accorded with the experimental results. It is shown that the numerical analysis simulating data is coincident with the testing one, which offers technical support to optimize the plate rubber support. The results show that the theory is available for the flexibility analysis of sandwich composite materials of box nose girder.
