Optimal Design of Conveyor Truss Structure Based on Response Surface Methodology

In order to give full play to the load-bearing performance of the conveyor truss, a pipe belt conveyor truss structure is optimally designed based on the response surface methodology. A central composite design (CCD) is used for sample point acquisition, and the response values of the sample points are obtained by using finite element method to construct a second-order response surface approximation model with mass, maximum stress and maximum deformation. The response surface model was optimized using genetic algorithm with the truss section parameters as the design variables, the mass as the objective function, and the strength and deformation as the constraints. The results show that the mass reduction ratio of the optimized conveyor truss reaches 20.92%, and the optimization effect is significant to achieve the purpose of lightweight.
