Dynamical modeling and optimization of mechanical system is a multi discipline complex problems. This paper deduced Lagrange equations based on 4-DOF one-sided variable cross section roll-forming system and proposed the particle swarm optimization with negative gradient. The mechanical parameters of roll-forming system are optimized by using this algorithm. Optimization results show that the dynamic performance of the roll-forming system has been effectively improved. The algorithm provides theoretic foundation for the optimization design of the roll-forming system.
