TLJ900型架桥机后支腿的结构优化设计
Introduction:
Bridgeengineeringisanimportantfieldofcivilengineering,whichinvolvesdesigningandconstructingstructuresthatspanacrossrivers,valleys,andothernaturalbarriers.Amongthevariousequipmentusedinbridgeconstruction,bridge-buildingmachinesplayavitalroleinensuringthequalityandefficiencyoftheconstructionprocess.TheTLJ900bridge-buildingmachineisonesuchmachineusedinbuildingbridgesacrossriversandotherwaterways.
TheTLJ900bridge-buildingmachinecomprisesofseveralsubsystems,includingthesupportinglegsofthemachine,whichprovidestabilityandsupportduringthebridgeconstructionprocess.Inthispaper,wewillfocusonthedesignoptimizationoftherearsupportlegsoftheTLJ900bridge-buildingmachine.

IdentificationofDesignProblems:
TheprimarydesignproblemwiththerearsupportlegsoftheTLJ900bridge-buildingmachineistheircurrentload-bearingcapacity.Thecurrentdesignofthelegsdoesnotallowthemtobearthefullweightofthemachineandthebridgedeck.Thisresultsininstabilityandreducedproductivityduringtheconstructionprocess.
FormulationofDesignObjectives:
Toovercomethedesignproblems,thefollowingdesignobjectiveshavebeenformulated:
1.Toincreasetheload-bearingcapacityoftherearsupportlegsoftheTLJ900bridge-buildingmachine.
2.Toensurethatthemachine'sstabilityisnotcompromisedduringthebridgeconstructionprocess.
3.Todevelopadesignthatiseasytomanufactureandmaintain.
DevelopmentofNewDesignConcepts:
Toachievethedesignobjectives,severalnewdesignconceptshavebeendeveloped.Thefollowingdesignconceptshavebeenproposed:
