Background The method is characterized in that a virtual environment is constructed to simulate the mapping relation between a stand operation instruction and a roller motion path, the method is a technical means commonly used in the industry, setting parameters of a rolling mill stand are generally collected, and the spatial displacement of a roller in the virtual environment is regulated in real time according to the operation instruction, so that the geometric evolution of a rolling process is presented at a visual terminal, however, the metal rolling process involves physical deformation under extreme load, the rolling mill stand generates physical yielding, namely bouncing effect, in a stressed state, the actual gap of the roller deviates from an initial setting position due to the characteristic, the existing interaction logic is generally based on an ideal rigid body model, the instruction flow is directly equivalent to the displacement of an executing mechanism, the intervention of the comprehensive rigidity of the system on the feedback precision is not considered, when the load fluctuation is generated in a production environment, the interaction terminal cannot reflect the nonlinear deviation of the roller gap after the stress, the virtual feedback logic and the physical real state are disjointed, and the intervention of the process parameter on the size of a final product is difficult for operators to perceive through a virtual system. In order to improve feedback precision, the industry tries to introduce a high-order nonlinear mechanical operator or a finite element analysis model, although the method can fit complex mechanical evolution, the related large-scale calculation occupies mass processor resources, so that time delay is generated by an interactive link, for an industrial interactive system requiring sub-millisecond-level response, the synchronism between instruction input and feedback signals is destroyed by the hysteresis of data processing, in addition, the contradiction between response speed and simulation precision cannot be solved from an architecture level by simply relying on increasing calculation force, so that the stability of feedback logic is difficult to maintain when the system is used for coping with transient impact load or multi-frame cooperative disturbance, besides the physical yielding influence of a hardware frame structure, software control and the interactive logic level, the traditional simulation scheme is single in exposure data processing dimension and difficult to consider a short-circuit board, for example, the Chinese patent with an authorization bulletin number of CN119784982B discloses a virtual character interactive design generating method based on multi-mode perception, response and deviation data evaluation interactive performance is carried out by action capture and interactive test, the method belongs to the aspect of behavior logic surface simulation, service logic surface simulation is orderly distributed, the situation is separated from the transient impact load or multi-frame cooperative disturbance, the dynamic stress is difficult to realize the dynamic fluctuation of the dynamic stress, the dynamic stress is difficult to restore the complex dynamic stress load dynamic stress has a stable phase, and the dynamic stress has no relation is difficult to be balanced, and the dynamic stress has no problem to realize in the dynamic fluctuation of the dynamic stress has a complex dynamic stress-state, and has a dynamic stress-state interaction relation. Therefore, how to utilize the electric digital data processing means and establish a mapping logic which gives consideration to both load deformation compensation and dynamics association on the premise of ensuring the real-time response performance of the system, and the reduction of the virtual interaction system to the rolling physical essence is realized, so that the method and the system are the technical problems to be solved.
