盆式橡胶支座与垫石组合的接触有限元分析
Finite element contact analysis of the pot rubber bearing and pad stone combination
摘要
Abstract
In this paper, based on the engineering background of high speed railway bridge bearings and pad stone, the structure of pot rubber bearing and reinforcement of pad stone was introduced in details, nonlinear fi-nite element analysis of mechanical properties of bearing steel basin and reinforced concrete pad stone by using ANSYS program, analysing about the key technologies that unit selection, material definition, the establishment of models, and the contact friction between bearing and pad stone in the numerical simulation of structural process. Research on the mechanical behavior of the bearing pad stone combination varies in the loads, and based on the single bearing pad stone as an example, discusses the different plate thickness, different bearing pad stone height on the influence of the stress state and deformation of the composite structure. The results show that the finite element analysis could well simulate the mechanical performance of bearing pad stone combination;The change of the main design parameters have a corresponding impact on the stress of the bearing pad stone combination. Thesis research results can provide reference for bridge engineering applications.关键词
