| 英文摘要 |
| The composite sheet corrugated roll rolling technology is a revolutionary technology, the roll shape curve of
corrugated roller is a cosine function curve. During the rolling process of composite plate, the nonlinear damping of the
rolling interface and the nonlinear stiffness between corrugated roll and flat roll may cause principal resonance, resulting
in the fluctuation of roll gap. Considering the nonlinear damping and nonlinear stiffness within corrugated interface of
corrugated rolling mill, establish the mathematical model of the two-freedom-degree vertical nonlinear of roller system in
corrugated rolling mills. The stability of roller autonomous system of corrugated rolling mill is discussed by using singular
value theory. The approximate analytical solution and amplitude-frequency characteristic equations of principal resonance
of roller system excited by corrugated interface are carried out by using the multiple-scale method. The influences of
nonlinear stiffness coefficient, nonlinear damping coefficient, system damping coefficient and rolling force amplitude on
vibration are analyzed. The time-delay feedback controller with linear and nonlinear interactions is designed to control
the principal resonance of the corrugated roll system, and the correctness and feasibility of the controller are verified by
numerical simulation. |
