Abstract :
In order to make the design plan better reflecting the user requirement, and change the design manner from experience-driven to performance-driven design of the hydraulic press, a method of calculating the correlation between the user requirement and hydraulic press performance is proposed;Map between them is established by use of rough set theory. The result shows that this method can reflect the user´s requirement and the relevance performance of hydraulic machine objectively, and has certain significance to increase the quality of the hydraulic design.
