Secondly, the paper is expanded from follow three aspects: the virtual design, the virtual process and the product data managementduring the developing the torque converter. Applying the key technique of concurrent engineering---design for function, design for assemblyand design for manufactureof the method of design for "X", the virtual design of the torque converter is accomplished in CATIA V5. Then the model constitution and the simulation of virtual process of the torque converter is done in CATIA V5, including the model constitution and the simulation of 5-aixe NC virtual process of the vane, the model constitution（material:PVC） of the idler pulley rapid prototypingand the virtual assembly and the motion simulation of the torque converter, etc. 3-D data exchange between various CAD systems is realized by using STEP standard. The lever of classing the character model of the torque converter is given. And the access authorization is set up and given to manage the partners' reading/writing the product data.
