“…It can be seen from Figure 15 that the wall thickness of the frame rail and the wall thickness of the frame Structure optimization beam have a relatively large influence on the quality, and the blue portion is the lightest. Sensitivity analysis is performed in Workbench for each design parameter corresponding to the objective function, that is, the sensitivity of structural performance parameters to changes in design variables (Cai et al, 2018;Wu et al, 2016;Yuan et al, 2019;Amine et al, 2019;Fu et al, 2018). Figure 16 is a histogram of global sensitivity analysis of model parameters for mass and stress.…”

Purpose As a key part of the algae removal equipment in the middle route of South-to-North Water Diversion Project, the static analysis and dynamic analysis are carried out for the structural characteristics of the frame. The paper aims to discuss this issue. Design/methodology/approach First, the model is constructed for analysis. Second, finite element analysis are carried out. And finally, test designed is used for the construction. Findings The optimization scheme that minimizes the quality under the condition of satisfying the allowable stress is found, and the quality is reduced by 6.88 percent. Originality/value The paper is based on the occurrence of seasonal algae in the main channel of the Middle Route of the South-to-North Water Diversion Project, an automatic algae-removing equipment was designed.
