Metodología de diseño aplicada en dispositivo de pruebas en pistones

Abstract

As part of the development and manufacture of engine pistons used by the automotive industry, a series of laboratory tests are carried out that include: Mechanical, metallographic and chemical analysis of the material, dimensional verification, final weight and piston finishes finished, tests on the engine dynamometer of the finished product, etc. The technological development department of an automotive piston manufacturing company, as part of the quality assurance process of its products, has established the need to assess the compressive and fatigue resistance of pistons, both at room temperature and at temperature normal operation of an internal combustion engine. The equipment proposed to carry out these tests is an hydraulic servo machine, which has the capacity to apply dynamic load and static load, with which extreme piston operating loads can be simulated. For this reason, the design goal of this work is to design a device with which the test specimens (pistons) can be held in the machine, in order to perform fatigue and compression tests and in which, the heat can be heated piston at the required test temperature.
