Diseño y simulación de un remolque de doble eje para transportar "la casita del buen vivir (CBV)" del proyecto de educación ambiental del Ministerio del Ambiente del Ecuador

Abstract

The “Casita Del Buen Vivir, CBV” is a small house that works with alternative energies, it is part of an educational project of the Ministry of Environment of Ecuador and it is transported by different types of roads. It is important that the trailer system meets all the conditions and characteristics of proper use and operation. The suspension system is one of the key factors in the design of the trailer that will transport it. The document begins by explaining the advantages of transporting the "CBV" in a trailer, in addition to establishing each of the components of the “CBV”, conditions of use, and the characteristics of the National Road Network where will the “CBV” transit. In the following chapters, conceptual and detail design is developed, design uses tools such as functional analysis and concurrent design. In the detail design stage, the ASD permissible stress method was used for structural elements, where safety factors of 1.67 were used, and as deflection for floor members a value less than the value of the unbranched length divided for 360, for the rest of mechanical elements the maximum strain method was used, the critical excitation frequency values for the suspension system doesn´t reach the natural frequency value, consequently the system does not go into resonance, this is the result of a vibratory analysis. Finally, the results of the project are reflected in the workshop and joint plans.
