Optimización en el proceso de fabricación por impresión 3d de la manija del elevador de vidrios del vehículo Chevrolet Aveo Family para la mejora de propiedades mecánicas y térmicas

Abstract

The automotive industry after the declaration of a pandemic by the World Health Organization has been affected in the imports of vehicle parts and spare parts, for this reason the present investigation aims to provide an alternative solution through the 3D printing of the glass lift handle, which is evaluated in the Inspire software where its mechanical and thermal properties were verified prior to printing. For this reason, before validation, the design of the glass lift handle is carried out in the Inventor software, then the optimization is simulated in the Inspire software and its respective analysis of the mechanical and thermal behavior, the study is based on the application of the entropy method, standard results method, statistical variation method, multicriteria method and copras method, with the materials selected as the best alternatives to replace the original, among them we have PLA, PC and PVC. As a conclusion of the research, it can be mentioned that the most suitable material to replace the original is PLA because it has excellent mechanical, physical and thermal characteristics. Through Inspire it was possible to change the original design of the handle obtaining an optimized proposal whose weight is 2.7% lower, in addition the 3D printing time is reduced 8.3% compared to the original model, the analysis of the mechanical behavior indicates that the load that produces tension generates 3.3% less in the value of the Von Mises effort, however, in the bending loads the effort is increased by 17.3%. With this study it can be mentioned that the alternative material PLA is ideal to replace the original ABC-PC, the benefits of the analysis help to have an alternative to industrial production, giving a solution to imports that are restricted.
