Abstract: The rigid visco – plastic finite element based forward and inverse simulation technique used for perform design is introduced. This technique is applied to the perform design of a complex track link forging process. The design object from required final forging to perform forging is realized directly. The designed busting shape and buster die shapes result in a less finisher die wear, reduction of the material waste as flash and improvement of the positioning stability of the busting in blocker die cavity. The designed result is applied to industrial production and good economic benefit is achieved.
