The Finite Element Analysis And Optimization Design Of Metal Structurein In 1600t Movable Support System

MOVE SUPPORT SYSTEM(MSS)is the construction machinery which uses their template to move span by span and pour the concrete beam.MSS is widely used in road and bridge construction projects.The characteristic of the MSS is that can be used continuously after field assembly,which makes high construction efficiency,high accuracy and high fitness for multiple and complex working conditions.In this paper,1600 t Movable Support System developed by one co MPany is considered as the research object.Based on platform of ANSYS,use algorithmic processor description language(APDL)to achieve modeling and finite element calculations of Movable Support System.Summarize the analysis steps of Movable Support System and propose solutions to the encountered problems.Focusing on the situation of moving through the hole,consider 2m as step length and analyze process of moving through the hole;make sure the changes of stress and reaction force of MSS;study the law of limit stress curve when MSS builds concrete beam and moves through the hole.As for bolt connections in each section between girder and guide beam,use SolidWorks to establish 3D entity of each joint and import it to the Workbench to do the finite element simulation calculation.Check the stress distribution and proofread the security of high-strength bolts.Based on ANSYS,use parametric optimization to optimize the main girder and truss beams in order to reduce their weight.Use APDL language to establish finite element model of external formwork system and then do the analysis and optimization.The parametric finite element analysis method can be more comprehensive and accurate in guiding the design of Movable Support System.
