Abstract: Carried out the research into optimized design to abrasive wheel that is one of the main parts of the LM8×2 vertical roller mill by ANSYS.First, carried on topology optimization to abrasive wheel, definition the best shape and major optimized dimensions, and determined the direction of the optimization of the abrasive wheel.Later, according to the data of abbrasive wheel about topology optimization carried on size optimization, trying to keep constant of maximum stress and displacement of abbrasive wheel, as far as possible the reduction of the weight of abbrasive wheel.Analysis results show that the weight of the applications reduce for 3.332 t at least, under keep constant of maximum stress and displacement condition.
