Lightweight design of inner hub of coated steel strapping machine based on topology optimization

Abstract

Aiming at the current situation of the demand for low energy consumption, long life and high efficiency of the coated steel bar strapping machine, topology optimization and orthogonal test method are combined to carry out lightweight research on the inner hub of the strapping machine. Based on the results of the static analysis, and taking the minimum structural flexibility as the research objective, the optimized dimensions are designed and the topology optimization model of the inner hub is established, the orthogonal test is simulated by ANSYS, and the least-squares regression equation is established to obtain the optimized mathematical model of the inner hub. The static analysis of the optimized inner hub model is carried out, and the comparison results show that the weight is reduced by 23.06% under the requirement of meeting the working needs of the inner hub.
