Abstract ： In order to explore the rule of rotational performance of composite grinding wheel with brazed segments，the classcal analysis module of finite element software ANSYS isused to study the rotational performance of composite grinding wheel with different placement angles. 181 groups of rail grinding composite grinding wheel models with 30 brazed diamond segments are established in every 1∘ interval， and the rotational performance of each model is simulated to determine the rotational stress and shape deformation of the composite grinding wheel surface at various angles，as wellas the rotational stress and shape deformation of the brazed segments at different angles.The results show that with the angle of the radius of the flat grinding wheel as the symmetricalaxis，the surface stressand deformation of the grinding wheel show anobvious symmetrical transformation law with the different placement angle of the brazed segment. The maximum stresson the surface of the grinding wheel varies between 11.9MPa and 12.4MPa ，while the minimum stress varies between 1.13 MPa and 1.29MPa . The placement angle of the brazed segment has limited effect on the maximum deformation ofthe grinding wheel surface.The rotational stress on the brazed segments within the grinding wheel is significantlyhigher than thatonthesurfaceof the grinding whel； however，the displacement is notably constrained bythe grinding wheel itself.In this case，the optimal placement angles of brazing segments in the manufacture of composite grinding wheel are 60∘ and 120∘ ：
