Applications of Finite Element Modeling in Industrial Forming Processes at the Timken Company

Abstract: Advances in stabilized finite element methods for bulk and sheet metal forming processes AIP Conf.Abstract. At The Timken Company, finite element modeling has been utilized successfully to design, improve and optimize metal forming processes in many areas from steel making processes for long products and tubes, and forming and shaping of discrete parts. It is very challenging to apply the finite element modeling to most incremental forming processes due to continuously changing contact conditions between workp… Show more

“…The accuracy of the implicit formulation is slightly less than the explicit formulation -contrary to the conventional experience that static implicit formulations are generally more accurate. The model is also discussed by Sawamiphakda et al [174] as part of their suite of finite element models used by the Tirnken Company.…”

“…German scholars like Pehle, Thieven, etc., adopted the three-dimensional FEM to simulate the production process of the stretch reducing in the Mannesmann plant using the commercial software, and studied the three-dimensional deformation, contact problems, the impact of the roller profile and the tension on the stretch reducing process, especially the variation of the tube wall thickness and so on [5]. The specialists of Timken company in USA, such as Gulyayev, Sawamiphakdi, etc., studied the problems of the FEA model to simulate the stretch reduc- ing process, the contact problems, the variation of the tube wall thickness and so on [6,7]. Chinese experts, Du Fengshan, etc., simulated the production process of the stretch reducing of the Baosteel company using self-programming three-dimensional elastic-plasticity FEM software.…”

“…As a result of a small range of applications for helical wedge rolling in industrial process, there are only a few recent studies devoted to this technique. The studies mainly concerned the FEM-based numerical modelling of rolling processes for rings [36,116] and balls [10,114,115,123,132,138] as well as the design of tools used for these processes [10, 100,122,147,164].…”
