Rehabilitación e implementación de un sistema de salida de datos digital al dinamómetro P-400B del laboratorio de maquinaria pesada de la carrera de Ingeniería Automotriz.

Abstract

The present work was the repair of an analog dynamometric test bench to test tractors and motor cultivators, and the subsequent implementation of a digital data system. With the respective verification of the operation of its mechanical elements, also to the proper repair or fitting of certain parts and pieces, it was possible to obtain a correct operation of the equipment in relation to its initial specifications. In addition, a bibliographic study was performed on the operating parameters of an engine with agricultural utility in order to better establish the technical data provided by the manufacturers and verified in the equipment. A signal conversion system was implemented to fulfil the goal of presenting a new form of data output and printing, debugging the signal to avoid unwanted interference, improving accuracy and ensuring reliable results. The results obtained are presented in a more useful way in the data sample interface which also provides the necessary physical backup through its printing system. In order that the bench be technical and didactic utility for the School of Automotive Engineering, a user manual in Spanish was prepared and delivered, which details the required elements for its operation, the procedure to enhance the tests and the necessary considerations for the correct preventive maintenance of the equipment.
