Lightweight Design of Formula Racing Sprocket based on Topology Optimization Method by Jixiong Li, Jianliang Tan, Guojie Mai

“…Abstract In order to obtain lightweight formula racing sprocket， the topological optimization method is introduced into the design of sprocket structure， the mathematical model of lightweight optimization design is constructed， and the geometric model of initial sprocket design is optimized by reducing the weight three times， and the sprocket with 49.59% mass reduction is obtained. …”
