摘要
Abstract
The size and shape of track were optimized to adapt to changing of driving wheel and track frame in the heavy excavator.The structure characteristics of the track were discussed.The casting process was designed,optimized and determined by the solidification numerical simulation with analysis software.The structure and the casting process of track were verified by small batch production test.The results show that the shrinkage defects were effectively eliminated by using big riser and chill;the size,shape and surface quality of the track casting is conformed to the requirements of the drawings and specifications.The product assembly meets the requirements of design and operation.关键词
