Diseño y construcción de una plataforma de pruebas de inclinación (tilt test) según la normativa vigente aplicado a un vehículo Fórmula SAE de la Carrera de Ingeniería Automotriz

Abstract

The objective of this work was to design and manufacture a platform that allows performing the tilt test (Tilt Test) in a single-seater vehicle of the Automotive Engineering Career of the Escuela Superior Politécnica de Chimborazo and verify compliance with this test according to the regulations of the SAE (Society of Automotive Engineers). Prior to the manufacture of the platform, with the help of CAD/CAE software (Computer Aided Design/Computer Aided Engineering), several platform models were designed and a study of the behavior of the system was carried out by applying a static load of 5000 N, simulating the actual operation of the mechanism with the use of ANSYS software. Based on the data obtained by the CAE software, the fourth design was chosen as a model for its manufacture, since it provides good resistance to rupture under load with safety factor of 1.6 when it is at an angle of inclination of 45 degrees and 1.7 to 60 degrees; In addition, the manufacturing cost was low compared to the other designs. It is concluded that the model of the platform that was built used a 50x3 mm square profile, in addition, the tilt test was carried out satisfactorily and it was verified that the Formula SAE vehicle complies with the static requirements as stipulated in the regulations. It is recommended that when carrying out the simulations, a good meshing quality be used to obtain good data that is capable of resembling reality.
