Dynamic Analysis of Hydraulic Roll Bending System for Asymmetric Loading

Abstract:

To increase quality of the final product, high-precision rolling mills have been used in the modern steel making industry. Hydraulic bending system is widely used to improve the precise of the rolled plate products. In this paper, the dynamics model of hydraulic bending system for asymmetric load is built, and the simulation method is proposed accordingly. The simulation is realized in MATLAB/Simulink. Then an illustrative example is given for demonstrative of the model. Also, the effects of the design parameters are analyzed and some nonlinear factors, such as, flow characteristic, load damping of servo valves, are considered in this simulation. It’s believed that this research will help to analysis and optimize the design of roll bending system
