Abstract
En este presente trabajo se realiza el diseño y montaje de un banco de pruebas multidisciplinario con fines didácticos de un motor Peugeot con denominación EC5, a partir de la disposición del motor estándar ya en funcionamiento sobre una plataforma en el laboratorio de Mecánica donde estaba limitado solo a la posibilidad de encendido y observación de su funcionamiento. El banco de pruebas cuenta con tres partes bien definidas: medición de potencia, sensores de motor y red de comunicación CAN-BUS del motor. Se lleva a cabo el estudio de estos tres
sistemas previamente de forma profunda en el transcurso del proyecto para entender los principios de funcionamiento, el comportamiento ante diferentes condiciones y su respectiva verificación. Para diseñar el sistema de medición de potencia se procede a analizar los diferentes dispositivos relacionados al frenado de un motor y evaluar el más conveniente para el motor en cuestión. Se instala un dinamómetro hidráulico que utiliza agua como fluido de trabajo. En conjunto, se dispone de los elementos electrónicos referentes a la medición de sus parámetros y un software para almacenarlos y concluir con la gráfica de potencia que identifica al motor. Se construyen dos tableros en el frente del torpedo del banco de pruebas, uno para pruebas de sensores del motor y otro para la red de comunicación de CAN-BUS, donde se tiene a disponibilidad los puertos de los terminales de cada sistema. El fin de los mismos es facilitar mediciones y su respectiva recolección de datos. Para complementar, se redacta un manual de uso integral para el banco de pruebas, donde se dispone de la información necesaria para el mantenimiento, pasos para su puesta en marcha e instrucciones de los procedimientos que se pueden llevar a cabo en las pruebas de forma segura.
In this present work, the design and assembly of a multidisciplinary test bench for teaching purposes of a Peugeot engine with denomination EC5, from the disposition of the standard engine already in operation on a platform in the Mechanics laboratory where it was limited only to the possibility of ignition and observation of its operation. The test bench has three well-defined parts: power measurement, motor sensors and CAN-BUS communication network of the motor. The study of these three systems is carried out in depth in the course of the project to understand the operating principles, the behavior under different conditions and their respective verification. To design the power measurement system, we proceed to analyze the different devices related to the braking of an engine and evaluate the most suitable for the engine in question. A hydraulic dynameter is installed that uses water as a working fluid. As a whole, we have the electronic elements related to the measurement of its parameters and software to store them and conclude with the power graph that identifies the engine. Two panels are built on the front of the torpedo of the test bench, one for testing the engine sensors and the other for the CAN-BUS communication network, where the ports of the terminals of each system are available. The purpose of these is to facilitate measurements and their respective data collection.
