Structure optimization of the frame based on response surface method

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.
