摘要：
Tension levelers are widely used in the continuous production line of wide strips in modern metallurgical enterprises. The core problem of its development is the optimal matching of the power of the drive motor of the tensioning roller group arranged before and after the straightener. Based on the theory of power balance method and bond graph method, the power bond graph model of the transmission system was established. Taking the in-service differential tension straightener for the production line of cold rolling plates in a modern steel company as an example, the dynamic characteristics of power transmission were studied. The results showed that when the tension straightening drive system produces strips of different specifications, the power fluctuation probability of the main transmission motor increases at the early start-up low-speed stage, which leads to the increase of the component deformation and the decrease of the safe service probability of the equipment. The MAPE (mean absolute percentage error) of the model calculated by the field industrial test is 9. 3%, which verifies the accuracy of the model. © 2023 Northeastern University. All rights reserved.
