Comparison of two FEA-based approaches in prediction of workpiece-fixture static behaviour

Grochowski M., Jedrzejewski J.

Journal of Machine Engineering

2008

Vol. 8, No. 3

54--65

Simulating of workpiece and fixture behaviour is commonly done with the use of Finite Element Analyses. In the most, if not all, cases researchers usually use traditional implicit integration scheme FEM codes (e.g. ANSYS, ABAQUS/Standard, NASTRAN, FEAP). In this paper a different approach is proposed. FEM code of ABAQUS/Explicit, based on explicit integration of equations of the motion is used to predict workpiece behaviour during alignment and fixing process in quasistatic state. Comparison of results obtained using both implicit and explicit techniques is also presented, results and differences are discussed.
