Grinding wheel for curved steel rail grinding vehicle and preparation method of grinding wheel

The invention discloses a grinding wheel for a curved steel rail grinding wagon and a preparation method thereof, the grinding wheel comprises an aluminum substrate, a high-strength transition layer and a grinding layer, glass fibers are uniformly placed in the high-strength transition layer, and the aluminum substrate is embedded in the inner circle of the high-strength transition layer. Compared with the prior art, the grinding wheel has the positive effects that the grinding wheel for the curved steel rail grinding vehicle adopts a multi-layer structure, the internal aluminum matrix is ensured to be tightly combined with the high-strength transition layer, the mounting size is ensured, and the impact of a main shaft on the grinding wheel is reduced; a high-strength transition layer is obtained in the middle part through a specific formula and pressing and hardening processes, and the high-strength transition layer ensures that the large-size curved surface steel rail grinding vehicle is not broken when bei
