Theoretical Research for Determining the Static and Dynamic Rigidity of the Machines before Drafting the Remanufacturing Project

Abstract

By the developed applicative research we look for setting up a procedure for dynamically diagnosing the technological equipment proposed for remanufacturing. Actually, this paper presents some of the results of the research carried out for the establishment an analysis method of the non-functioning technological equipment structure, using the Finite Element Analysis, for stating the own vibration modes, thus based on the structure own frequencies to be stated the maximum critical rotation up to the new equipment would function in the imposed quality and safety conditions. With the proposed procedure we could exactly state the structure own frequencies that yet appear within the working frequencies band of the analyzed technological equipment, and thus we could find the revolutions at which the mechanic system could enter into resonance.
