【Abstract】 After the major idea of configuration design for automobile differential based on criterions of automobile design were expounded, the thoughts and results of 3 -D modeling of parts for differential based on feature were presented by Pro/ Engineer software. Finally, the method and steps of 3-D virtual assembly modeling were expounded. Precise 3-D modeling of parts for differential are helpful to improving precision of NC, and 3-D virtual assembly are helpful to detecting and setttling problems of configuration design, so time of develoment for differential manufacture will be shortened and cost of the design will be reduced.更多还原
