| 英文摘要: |
| 3D roll-forming for high strength steel sheets is a new technology at present. Double racks gear 3D roll forming machine developed by our research group can be used to perform variable cross section roll forming for high strength steel. In the paper, a dynamic model of 8-DOF double rack gear 3D roll-forming machine is established by the method of Lagrange equation. The expression of the angle acceleration of the system response is obtained by solving the dynamic equations. Through an actual engineering example, the dynamical characters of the 3D roll forming machine are revealed. The results can support the design of 3D roll forming machine. Meanwhile，the research will play an active role in the development of control system. |
