Abstract
The present work shows the structural behavior of a bus body under frontal impact by explicit analysis of finite elements using LS Dyna software to propose a modification to the Ecuadorian Technical Regulations NTE INEN 1323. For this purpose, different tests were carried out to show the resistance to different types of Design gas proposed in national regulations. Therefore, they are reviewed national and international regulations that provide specific data to achieve this study. In addition, the results were validated by comparing a physical tensile with a computational one, where they were applied analysis criteria for the bus impact test. Convergence was obtained through results between the two tests with a calculated error of 1.89%. Finally, it has been observed that the national construction body of buses is not designed to withstand frontal impact loads.
