Optimization Method of Hoisting Points Schemes Using Strain Energy Criterion

Abstract

The optimization method of hoisting point’s schemes using strain energy criterion was studied in this paper. Firstly, the finite element model of complex steel truss hoisting was established and optimization analysis of hoisting point’s schemes for complex steel truss hoisting using strain energy criterion was accomplished. The calculation code which can make finite element analysis and optimization analysis of lifting point’s schemes based on strain energy criterion automatically. Then, lifting point’s schemes of complex steel truss hoisting were analyzed with calculation code mentioned above. The results indicate that, the optimization index using strain energy criterion is just strain energy criterion which is a more comprehensive and unidirectional index. Optimization analysis based on strain energy criterion changes optimization analysis of the lifting points schemes for complex steel truss hoisting from multi-target optimization into single-target optimization. The case study shows that this method is practicable and reliable and have good application prospect in hoisting points schemes optimization analysis with application to complex steel truss hoisting.

“…Compared to prior research [19,20,23,24], the optimization outcomes presented in this paper offer more practical insights for engineering applications. These findings were derived from a simulation optimization approach that focused on identifying the most hazardous points during hoisting operations under actual working conditions.…”

“…The findings presented in Section 3.2 indicate the necessity for the hoisting design to undergo further optimization. Additionally, studies have demonstrated that differential lifting point designs can cause stress and strain changes during the hoisting process [19,22,23].…”

“…Finally, in the hoisting of large-span thin-walled equipment, the differential design of the lifting point had been shown to cause changes in stress-strain during the hoisting process [20][21][22][23][24][25]. While some research has focused on selecting the position of the lifting point, there is a need for more studies on optimizing the lifting point position [20,23].…”

Furthermore, existing research has not considered the stress-strain situation during the dynamic hoisting process, which may lead to suboptimal results under actual working conditions.…”
