Performance Analysis of Anti-Collision Device for Foam Aluminum Sandwich Plate Pier
[Purposes]In order to meet the structural design and quality requirements of bridge pier anti-collision devices,and improve its service life and comprehensive performance,a anti-collision device for foam aluminum sandwich panel was designed and its performance was analyzed.[Methods]According to the original bridge pier anti-collision device,the anti-collision device of foam aluminum sandwich panel is designed according to the principle of equal quality.By using ANSYS Workbench for display dynam-ics analysis,simulating the process of a vehicle colliding with a bridge pier,and extracting the time his-tory curve of stress and deformation throughout the entire collision cycle,this paper determines the maxi-mum stress and deformation generated during the dynamic process.[Findings]Under the impact load,the maximum stress of the overall structure is 491.02 MPa,and the maximum deformation is 280.31 mm.[Conclusions]After the above simulation analysis,it can be concluded that,the superiority of the foam aluminum sandwich panel structure in anti-collision performance provides technical support for the sub-sequent production of foam aluminum sandwich panel pier anti-collision device.
