This paper presents a numerical method with a preciss calculation which can be controlled based on the high speed of calculation of the electronical systems. This process allow the introduction, if is necessary, to another functional limitations.

The advantage of such a method is that the changing of the casting piece parameter values induces an instant changing of the semiforms at the new dimensions of the casting form.

The goal of this study is optimization of the geometrical parameters from the viewpoint of rigidity. The computerization simulation was applied to 150 worm-gear drives The Annals of ''Dunarea de Jos'' University of Galati : Fascicle XIV MECHANICAL ENGINEERING, ISSN 1224 - 5615 2002-01-01T00:00:00Z http://arthra.ugal.ro/handle/20.500.14043/24461 The consolidation Equipment Work Devices Vibrations Frequency Influence about the Railway Stabilization Process Gaidoș, Aurelian In this work presented the experimental research realized on the stand in the laboratory. The experimental researches have as the goal the study of the influence the frequency vibration of the work device concerning the railway consolidation. The utility of correlations knowledge dislocation force and transversal displacement of the half-sleeper is obvious by offering information concerning the stabilization process of the railway superstructure.
