Abstract
In order to study the influence of friction and slip effect of bearing on transverse deviation of concrete curved beam bridge, the solid model of basin rubber bearing was established by ANSYS. Based on this, the stress and deformation of PTFE plate, basin ring, compressed rubber block and base plate were analyzed in detail; the vertical of the bearing was simulated by finite element method. The load-displacement curves are compared with the bearing capacity test results of 2.5MN basin rubber bearing completed by the Highway Science Research Institute of the Ministry of Transportation. The results show that the basin rubber bearing has stable mechanical properties, and the maximum principal stress, vertical compression deformation and radial deformation of the bearing under the design vertical load satisfy the design requirements; the maximum error between the calculated value and the experimental value of the vertical compression deformation is 4.8%, which verifies the accuracy of the finite element model and is for the follow-up. Foundation for analysis of friction and slip characteristics of traveling bearings.
