Parametric Finite Element Analysis for the Modular Expansion Device of Long-Span Bridge

Fang Wu, Jianwu Pan, and Minghua Zhou
Abstract—In order to research the cause of disease in modular expansion joints, in this paper, based on the secondary development, a general static analysis program has been compiledto facilitate the analysis of the integral finite element model of modular expansion joints. On this basis, the parameter analysis of modular expansion joints has been carried out using this program, mainly discuss the factor that affect the horizontal displacement of lamella. Moreover, the effect of the failure of sliding spring and control spring has been analyzed. The formula for the horizontal displacement of lamella is presented. The results show that the rigidity of control system and the condition of edge beam have a larger influence on horizontal displacement of lamella, then is friction coefficient of contact element, pre-tightening force and stiffness of sliding spring. Moreover, the failures of sliding spring and control spring are all close to the end of sliding. The research can provide scientific basis for the disease mechanism and the disease control of modular expansion joints.

Index Terms—Control spring, Lamella, modular expansion joints, sliding spring.
