Diseño y construcción de un equipo para ensayo de impacto de espejos retrovisores de motocicletas según Norma NTE INEN 2556.

Abstract

This study aimed to design and build equipment for testing motorcycle rear-view mirrors of subcategories L3, L4, and L5 (TRC1 code), following the guidelines of the NTE INEN 2556 Regulation; this test is one of the requirements that specifies the Regulation for the approval of rear-view mirrors installed on two- or three-wheeled vehicles without bodywork. To develop the research, bibliographic, experimental, exploratory, and explanatory methods were used to expand the information contained in the ruling used and the characteristics of equipment that performs impact tests using a pendulum. The conceptual design methodology determined the materials of the structure, the fastening system, and the impact system to obtain an optimal design of the equipment for testing; then, a design and simulation software was used to validate the materials selected for construction through the finite element method, the direct observation method was also used to verify the behavior of the rear-view mirrors tested. The results of the tests on the rear-view mirrors with and without approval mark were compared with what is described in the NTE INEN 2556 Regulation, evidencing the total destruction of the reflective surface of one of the rear-view mirrors despite having the approval mark. It is concluded that the review of other Standards and Regulations allowed to understand the testing process and find similarities between Regulations applied to different categories of vehicles. The hypothesis proposed for this project was verified. It is recommended to make the necessary modifications to use the test equipment on rear-view mirrors of other types of vehicles.
