Abstract

Roll forming is one of the important advanced metal forming processes. Simulation is an effective method to study the geometrical and the mechanical character of the strip deformation between the rolls. The spline finite strip method (SFSM) has been developed to simulate the cold forming process. The solution procedures of SFSM are given. The forming processes of four types of sections: electrical resistance welded pipe, channel section, channel section with outer edge and non-symmetrical channel section, were simulated by SFSM. The transverse membrane strain, longitudinal membrane strain and displacement of the deformed strip were obtained.
