Análise numérica de uma base para um compressor alternativo

Abstract

In this paper we present the design of a base that will serve as support for reciprocating compressor, as well as its drive motor. This design is based on a previous work, which required some improvements presented in the course of this work. In the present study, a numerical model by SolidWorks® tool and a modal analysis of the structure using the finite element method using the Ansys® Workbench tool, in order to find the natural frequencies of the structure and vibrational modes, searching for preventing future problems related to vibration such as resonance. The model has been improved over the original model, taking into account some construction factors that significantly influence the results of computer simulations. Besides the improvement of the original model, new models have been proposed, such that the attachment structure would fit the surface, reducing environmental influences on the dynamic behavior, resulting in an increase in their natural vibration frequencies. It also emphasizes that, at the end, among the various proposed models, two were considered suitable to be built, with the final choice being made according to other criteria such as ease of construction and availability of resources in the areas of campus, for example.
