Implementación de la quinta rueda óptica para la validación del requisito establecido en el inciso 5.2 de la NTE 1668 mediante la realización del ensayo de aceleración en plano para la carrera de Ingeniería Automotriz.

Abstract

The objective of this degree workwas the implementation of an electronic element that aims to verify compliance with subsection 5.2 of the NTE INEN 1668, the electronic mechanism is described in the aforementioned standard as "Fifth Optical Wheel", this element has as a purpose to check that the weight-power ratio of the buses built in the country are adequate, that is, the buses must reach a speed of 40 km / h in 22.5 s. The purpose of this project was to build a prototype known as the "Fifth Optical Wheel" consisting of two bodies, an electronic part and a mechanic that can work together to obtain the best possible result in each of the tests carried out. For the realization of the circuit, the most suitable elements were chosen so that in the future there are no problems, making tests of the circuit and each of its components, for the manufacture of the support the most suitable design was considered so that this does not influence the operation of the vehicle, for this reason it was chosen as the best option for the mechanism to be autonomous, for the realization of the tests of the mechanism all the conditions established in the: NTE INEN 1668, as this test should be performed on a flat surface with all fluids as fuel, refrigerant and others should be at their maximum levels allowed as this will give more accurate results. When performing the labor field tests it was possible to appreciate that the design of the mechanism support is adequate and does not show any failure in its welding points, in addition the electronic part worked correctly giving very good results in each of the practices.
