The invention relates to the technical field of double-roller cast rolling and rolling, discloses a modulation
force generation method for double-roller cast rolling and rolling, and aims to solve the problems that in the prior art,
motion synchronization depends on complex
control logic, errors are prone to being generated, and robustness is insufficient. The method is applied to a
system comprising a roller
system and a constraint, and the roller
system is composed of a first roller body and a second roller body which are oppositely arranged; the overall movement of the roller system relative to the fixed reference is defined as first movement, and the relative movement between the two roller bodies is defined as second movement. The geometric inevitability
coupling relation of the two types of motions is constructed by presetting a constraint structure: when any motion is actively controlled, the other motion is inevitably and passively generated under the action of constraint forcing. According to the
coupling relation, synchronous deviation is eliminated from the
structural level,
motion synchronization can be achieved without a
complex algorithm, the equipment structure is simplified, the control difficulty is reduced, the system robustness and synchronization precision are enhanced, roller body stress can be optimized, the process stability and the blank quality are improved, and the
coupling relation is suitable for double-roller cast rolling and rolling scenes.
