APDL language-based optimization of tower crane

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 model. The combination of calibrating of overall stability and single-limb stability and FEA and OPT is realized through extracting some paramete from FEA results, such as weight and axial force, etc. The realization of the key technology is discussed. A rapid optimization design of tower body is realized by developing corresponding program using ansys parametric design language (APDL). It has a referenced meaning for other optimization design of steel structure.
