Caracterización dinámica de una vía ferroviaria mediante un dispositivo de masa desbalanceada : diseño y simulación de un dispositivo de masa desbalanceada con un disco rígido y con precarga en su estructura.

Abstract

In recent years there has been a growing demand for cargo transportation, both for the industrial and urban sectors, due to this, the use of rail transportation has increased, since it can be applied for passenger transportation in the city as well as for heavy cargo transportation in the industrial sector, As technology has been advancing to a great extent, the materials that are usually used for the manufacture of the structure of the railway rails have also been advancing, due to new studies and tests that have been applied to determine and improve the mechanical properties of the elements that make up the rails. With the purpose of characterizing the mechanical properties of this structure, this work seeks to apply theoretically the application of mechanical energy on the rails, causing vibration and thus determine the degree of deflection that this would cause on the structure. Based on researches consulted we have obtained the parameters that will help us to achieve this objective, in recent researches we have obtained the values at which a structure of this type presents deformation before a system of unbalancing mass, the force parameters are between 10 KN with the use of an external mass subject to a disk which by means of a 15 KW motor will provide an approximate speed from 1800 rpm to 4800 rpm, As can be seen, the motor must be connected to the distribution shaft by means of a transmission system which acts as a shock absorber preventing the motor shaft and the distribution shaft from having direct contact, which could cause failures due to misalignment at the moment of transferring the power.
