Construcción de un chasis de karting KF4 bajo la normativa CIK FIA 2023 para el grupo ASU automotriz de la Universidad Politécnica Salesiana en el Distrito Metropolitano de Quito

Abstract

The present construction project of a KF4 karting chassis under the CIK FIA 2023 regulations, carried out for the Grupo ASU Automotriz de la Universidad Politécnica Salesiana en el Distrito Metropolitano de Quito, consists of the physical construction and detailed tests of the aforementioned frame. The first phase of this project focuses on the design of the kart through the use of SolidWorks software. Following this, it must be verified that the design complies with FIA regulations. Once the design phase is completed, manufacturing proceeds. where traditional manufacturing processes are used to materialize the proposed design, where the starting point is the acquisition of the material, followed by cutting, measuring, cleaning and preparing the ASTM A36 tubes, which are then joined using a MIG welding process. , forming a single assembly that would become the frame, followed by all that, the structure must be analyzed using non-destructive testing methodologies like him; analysis of strain gauges and penetrating inks, for the continuity of the beads the quality of the welds we use these penetrating inks, while to measure the rigidity of the frame we use strain gauges that help us in a real way compare the deformation it suffers the chassis against the loads that it is usually subjected to, also taking into account the torsion that it suffers when a kart is in running order. Simulating the real operating conditions of a kart chassis is quite complex, although it is true that simulation in ANSYS simplifies things a lot, resorting to new methods such as strain gauges is still a viable option since it turns out to be quite novel without so many complications when doing them. Once the real measurements are obtained in the laboratory vs. those calculated using software, the data become more consistent with each other, which allows more technical criteria to be given regarding the reliability of this frame. The processes used in the functional analysis of this chassis always sought not to damage the chassis with the aim of this frame becoming a platform for new projects.
