Finite element model of crossbeam of GMCU2060 gantry machine center is proposed, the static and dynamic stiffness is analyzed by using finite element analysis. The weak link of the crossbeam is discovered and a modification scheme is put forward for the design of the crossbeam structure. The analysis shows that the maximum deformation of the improved crossbeam is decreased to 0.03 mm and the first...
Optimization design of tower crane steel structure is very important for design technique development of tower crane. This paper proposes a kind of parametric optimization model based on Ansys OPT, combined with finite element analysis (FEA) and overall stability theory. The tower body is taken as an example to introduce the building process and the program structure of the parametric optimization...
According to the structure of beam components of bridge type five axis linkage gantry machining center model TH58, three-dimensional solid models were established and meshed by ANSYS software. Using component analysis from the model analysis theory, the finite element models were analysised on static force, vibration model and harmonic response analysis. As a result, beam components structure has...
The crane performance depends largely on its box girder structure. The problem of structure topology optimization for a box girder is investigated in this study. Firstly, a comprehensive analysis to box girder is given and a topology optimization model for the bridge crane girder structure is established. Secondly, based on the optimization model, the box girder is optimized with finite element software...
