| Abstract: | Dynamical modeling and analysis of mechanical system has a theoretical guiding significance in the further study and improving the system performance.In this study,a dynamical model,which is based on Lagrange equations,was established for a 4-DOF one-sided variable cross section roll-forming system.Through solving the differential equations of this system,the expressions for angular acceleration and angular velocity of driving motor are obtained.In the given loads,the curves of angular acceleration and angular velocity of driving motors were calculated.Therefore,it was suggested that the results in this study establish the foundation for the effective control of servo motor and optimization of system structure. |
