At present the study on the application of the topology optimum design in scraper conveyor is still under development. In this paper the topology optimization based on the Solid Isotropic Material Penalization (SIMP) is applied to the design of the middle pan, which can provide a valuable conceptual design scheme for the selection of the middle pan pattern. In conjunction with the homogenization theory and Finite Element Method (FEA), the mathematical models for designing the middle pan by maximizing the rigidity are developed in this paper. By applying the topology optimum design to the middle pan, the topology optimization based on the SIMP method is proved to be reliable and practical at the conceptual design stage of middle pan.

One kind of multi-void three-dimensional microstructure models based on homogenization method is constructed. Based on multi-void microstructure, the mathematical models for the topological structural optimization which takes maximizing the total potential energy as the objective function is constructed, then the Kuhn-Tucker optimality condition of the update method about the designs variable based on the porous microstructure can be gotten when optimization iterates. Finally, in explaining the employed algorithm an example is provided.

At present the study on the application of the topology optimum design in scraper conveyor is still under development. In this paper the topology optimization based on the homogenization method is applied to the design of the baffle on the scraper conveyer, which can provide a valuable conceptual design scheme for the selection of the baffle pattern. In conjunction with the homogenization theory and Finite Element Method (FEA), the mathematical models for designing the baffle by the minimizing mean compliance are developed in this paper. By applying the topology optimum design to the baffle, the topology optimization based on the homogenization method is proved to be reliable and practical at the conceptual design stage of baffle.
