Diseño, construcción y pruebas de una máquina para realizar ensayos de tracción en cuerdas de fibras sintéticas.

Abstract

The development of a local testing traction machine for the synthetic fiber cords has as objective to bring an adequate and economic solution that allows improving the quality control processes in the manufacturing of synthetic fiber cords, by accomplishing parameters of safety and precision that dictates the regulation ISO 2307. For the election of the machine alternative more adequate, criteria of concurrent engineering was employed, the deployment of quality function, with which the necessity of the costumer was captured into technique parameters that could be evaluated by the designer, as well qualitative, thus identifying the preponderant parameters, which are more influenced at the moment to design. The built machine has a local testing capacity of 5000 kgf and an 18-inch stroke, being able to essay propylene cords of till ¾ of inch, this is made by means of an hydraulic system, for the acquisition of data was used a DAQ 6009 and a software created in Lab View, the design of its structural elements was made by hand and the results were corroborated through ANSYS software. The final tests to verify the equipment precision was obtained comparing the test results in certified machines with the obtained results in the built machine, with the costs of an imported machine, which showed the convenience of the same.
