KINEMATIC OPTIMAL DESIGN OF A NEW ROLLING MILL: TWO SPs APPROACH
نویسندگان
چکیده
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.

In this paper, a manipulability analysis of a new parallel-type rolling mill, named ‘‘paramill,’’ in its conceptual design stage is investigated. The paramill considered uses two Stewart platforms (SPs) in opposite directions for the generation of 6 degree-offreedom motions of individual work-rolls. The objective of this new approach is to pursue an integrated control of the strip thickness, st...
متن کاملA New Temper Rolling Force Model for Dry Thick Strip Considering Fully Elastic Contact
Temper rolling or skin pass rolling is one of cold rolling processes composed of a horizontal pass cold rolling mill stand. In this process, the thick strip is subjected to very light reduction (0.5–4%) in thickness in the presence of high friction amplitudes. One of the basic parameters of strip rolling processes is temper rolling force. A new rolling force model has been proposed for temper r...

متن کاملBack-calculation of mechanical parameters of shell and balls materials from discrete element method simulations
Discrete Element Method (DEM) is extensively used for mathematical modeling and simulating the behavior of discrete discs and discrete spheres in two and three dimensional space, respectively. Prediction of particles flow regime, power draw and kinetic energy for a laboratory or an industrial mill is possible by DEM simulation. In this article, a new approach was used to assess the main paramet...
