Abstract

This research is about the application of the national standard RTE - INEN 034 (Ecuadorian Technical Regulation) - National Statistical Institute, and the international standards CEPE R80, (United Nations Economic Commission for Europe) -(Regulation

80) belonling to structures that allow to carry out tests on the anchorages of the seats of transportation of persons destined to interprovincial vehicles. The development of the bench structure and the JIG (Support structure) involves a series of parameters and national and international standards to consider. All these parameters, such as the shape and space of the structure, location of the elements of the pneumatic circuit, materials and processes have been applied to a computational model through the use of computer tools as MEF (Finite Element Method), using the static analysis by flat tension, allowing to establish a design and structural results adapted to the conditions of the respective test. In order to manufacture the bench structure and the JIG support, several process options were considered, such as the type of material and welding method to be used. However, the use of structural steel A36 as constituent profiles of the test bench was previously predefined. One of the main objectives was to build a functional static test bench, taking into account the cost of materials, manufacturing processes and above all that the test forces are executed according to the rules governing the structure. After analyzing the different parameters in the finite elements software, it is determined that the structure of the test bench can provide a considerable degree of security for the user, in addition to supporting the respective test loads produced by the elements of the pneumatic circuit. This test bench has the advantage of being built to support the realization of new projects related to the continuous improvement in the area of passenger seats and their anchorages.
