【Abstract】 According to the load-cases and structure shape of bucket-tooth, an optimization algorithm is proposed. Reducing weight of tooth-base for its connection function and reducing stress of tooth-tip for its digging function are the main optimization targets, structural dimension optimization of the tooth-base and structural shape optimization of tooth-tip are undertaken. An example of structural optimization of bucket-tooth is given. It shows that the bucket-tooth weight is reduced and its movement resistance is decreased, its wear resistance and service life can be improved and the cost can be reduced through the structural optimization design.更多还原
