The extensive application of aluminum alloy in the manufacturing of high-speed railway vehicle bodies has made high-speed railway vehicle bodies lightweight.However,the problem of gouging the sliding grooves in the process of vehicle body manufacturing has affected the production progress of the high-speed railway trains.Aiming at the problem of aluminum alloy chute pigging,an aluminum alloy chute pigging car is developed.The milling parameters of the car are optimized using a single variable method and a multi-objec-tive synchronous optimization method.The mechanism of aluminum alloy material removal is studied,and the working conditions of the chute pigging car are comprehensively analyzed.The finite element model is estab-lished for chute milling,and the appropriate milling parameter combination is determined through designing different parameter tests,which will lay a foundation for the subsequent research and development of the alu-minum alloy chute root cleaner car.
