REDUCTION IN WEIGHT OF HOUSING OF AXIAL MINE FAN IMPELLER WITH ROTATING BLADES

The study uses topological optimization techniques in design of the housing of an impeller meant for the increased rotational speeds in ANSYS. The objective function of the impeller optimization is the minimum yield, and the optimization parameter is assumed as the change in the interior volume of the structure under certain constraints imposed on the external geometry of the impeller. The optimization of the impeller housing shows that it is possible to reduce the weight of the power belt, and to make one web to be load-bearing and the other web to be thinner, or to switch to the impeller with one web. Moreover, the design can use some elements of a lattice structure.
