Transient Dynamic

Techniques are described for the transient dynamic analysis of nonlinear periodic structures. These techniques consider the special characteristics of periodic structures in conjunction with the pseudo-force approach using numerical integration to reduce computerized solution costs. Comparisons with a general purpose finite element code demonstrate the savings in solution costs.

Abstract. The magnetic levitation linear feed unit is a new type of machine features. In machining, the tool and workpiece interaction force will be delivered to the table and make the deformation, resulting in processing errors of machine tools, machining of precision and surface quality. In this paper we established three-dimensional finite element model of the table of feed unit, use the finite element analysis software ANSYS to analysis of the transient dynamic analysis of the pre-designed table and improve the structure of the table at the design stage and forecast performance of the table and provide a theoretical basis for structure optimization.
