Optimal Design of Disc Cutter Structure Parameter Based on Genetic Algorithm
Because of the situation that the disc cutter bearing seriously damaged in the cutting process, disc cutter structural parameters is optimized which mainly affect the force on the bearing. The disc cutter cutting edge angle, cutting edge width, transition arc radius and caulking ring width between the bearings are taken as design variables, and the minimum equivalent load on the bearing as the target, the optimization model is established. Genetic Algorithm (GA) is used in the mathematical model.Finally, the optimized results indicate that the equivalent load on the bearing reduces 21% compared with the actual structural parameters. So the optimization results effectively reduce the force on the bearing and extend the life cycle of disc cutter.
