摘要

In this paper, the manipulability analysis of a new parallel-type rolling mill "Paramill" in its conceptual design stage is investigated. Paramill uses two Stewart platforms (SPs) in opposite direction for the generation of 6 degree-of-freedom motions of each work-roll. The objective of this new technology is to permit an integrated control of the strip thickness, strip shape, pair-crossing angle, uniform wear of rolls, and tension of the strip. The forward/inverse kinematics problems are formulated. Two main kinematic parameters, the size of the base and the opening angle made of two neighboring joints for a given size of the work-roll, have been determined in the way that the force and moment transmission from the actuators to the work-roll is maximized.
