Rediseño de los sistemas de volteo instalados en los volquetes del Gobierno Provincial Autónomo de El Oro.

Abstract

In the present investigation was Redesigned the System of Rolling for the Trucks Brand Nissan belonging to the Autonomous Provincial Government of El Oro, justified by the need to promote rural development of the cantons in the construction of roads, sewers and paved, with the system of rolling installed in the trucks will optimize operating costs, minimizing the drawbacks of cessation, better safety for drivers and will provide better service for the community. The quantification of several models of systems of rolling, qualified in environmental variables of service, strength of materials of security, stability and others, allowed the selection of the alternative of the system more suitable to support different loads of impact, buckling or lateral forces and deformations to be submitted in the case of unloading of the materials in irregular areas, it was done a maintenance plan of the entire system avoiding mechanical and hydraulic failures. It was proceed to the tension finding, displacements, unitary deformations and safety factor by using a program of finite elements. It will apply the different components of the mechanical system from such results were selected the optimal materials for the redesign of the system. Different tests are highlight. It was shown that the selected model is ideal because all the elements are working mainly shear and to loads for fatigue and taking into account the most critical element which has a safety factor of 1.4 which is appropriate, in conclusion the mechanical system works under permissible conditions. The obtained conclusions and recommendations give rise and ensure compliance the proper functioning of the system.
