Ensamble e instrumentación de un banco didáctico para pruebas de arranque en motores de combustión interna Carlos Romero-Piedrahita Andrés Rodriguez-Valencia Mauricio Monroy-Jaramillo Ingeniería voltaje velocidad corriente banco de pruebas Motor de arranque La medición instantánea de velocidad angular en volantes de inercia se ha usado, entre otras aplicaciones, en pruebas experimentales de motores de combustión interna para diagnosticar fallas, particularmente se ha implementado para evaluar las curvas de desempeño de motores de arranque y el estado inicial de las baterías. El presente artículo se enfoca en el desarrollo de un banco de pruebas didáctico basado en volante para realizar el diagnostico de desempeño de motores de arranque hasta de 3 kW, arrancadores eléctricos de motores de combustión interna de hasta 3 litros de cilindrada, propios de automóviles comerciales. Se describen las características principales del banco diseñado: elementos mecánicos, estructurales y accesorios; captadores de desplazamiento angular, corriente y voltaje de arranque, sistemas de lectura, tratamiento y presentación de información. Se emplea un sensor inductivo para la detección de la posición angular de un volante de inercia dotado de corona dentada; la señal análoga es convertida a digital y procesada digitalmente en un código escrito en Matlab®. Durante el ensayo del motor de arranque de prueba, se determina la variación de la potencia eléctrica entregada por éste y la variación de la velocidad angular del sistema de carga (volante) desde su inicio hasta la estabilización. La información experimental adquirida permite construir y analizar los perfiles de comportamiento de velocidad angular, intensidad de corriente, tensión y potencia eléctrica instantáneas. La contrastación, frente a las formas de características de los motores de arranque comerciales, del comportamiento de las señales de voltaje, corriente y potencia consumida del motor de arranque probado en el banco construido, permiten concluir sobre la idoneidad del banco y de la metodología concebida para realizar pruebas didácticas de caracterización y diagnóstico de motores de arranque en el Laboratorio de Máquinas de Combustión Interna de la Universidad Tecnológica de Pereira. 2020 artículo científico 1657-4583 https://www.redalyc.org/articulo.oa?id=553768212007 https://www.redalyc.org/journal/5537/553768212007/ https://www.redalyc.org/journal/5537/553768212007/html/ https://www.redalyc.org/journal/5537/553768212007/553768212007.epub https://www.redalyc.org/journal/5537/553768212007/movil https://doi.org/10.18273/revuin.v19n3-2020004 es http://www.redalyc.org/revista.oa?id=5537 Revista UIS Ingenierías application/pdf Universidad Industrial de Santander Revista UIS Ingenierías (Colombia) Num.3 Vol.19
