    Not contributing to environmental pollution due to metal waste is one of the factors for which this project was carried out, and when it was developed, what was obtained is that a car that has already lost its economic value. as attractive, rescue these attributes. The project is based on the restoration and recovery of elements that have been discarded as scrap. The present work began with the visual damage inspection of a car that has great relevance throughout the world such as the Volkswagen Beetle, to later choose the elements that still have a useful life in the car and replace those that no longer; the engine was put into operation, its original bodywork was removed and a completely new one was attached, which has all the safety and comfort parameters. The bodywork was designed in 3D using specialized engineering software, which allowed us to incorporate all the details it contains, with the aim of facilitating its construction. For the simulation process, the design of the main structure was prioritized, which is why it began with its modeling, to later submit it to all its structural tests. The INEN NTE 1323 standard was used to examine the design under the load combinations exposed by the LRFD method. The development of the work allowed to apply the knowledge acquired in the race regarding the operation of an engine and the design of structures.

    Análisis de lesiones producidas en el vuelco de autobuses interprovinciales evaluadas según los criterios del reglamento N 95 de la comisión económica para Europa (CEPE) de las naciones unidas utilizando el modelo computacional antropométrico del maniquí ES-2 mediante el software Ansys Ls-dyna Research

    This work details the modeling process of the truss of an interprovincial bus, using the Ecuadorian technical standard NTE INEN 1668 - Intra-regional, interprovincial and intraprovincial for public passenger transport vehicles. The main purpose is to analyze injuries produced in the rollover of interprovincial buses evaluated according to the Regulation N 95 of the United Nations Economic Commission for Europe (UNECE). In the initial stage, a diagnosis of the current situation of bus bodies was made, which shows the level of compliance with the requirements of INEN 1323, which refers to the UNECE/ECE R66, which describes that body manufacturers who wish to homologate a bus model must carry out the bus rollover test, to guarantee that the survival space is not invaded. The research concluded that the use of two-point and three-point seat belts gave us similar behavior in the dummies when simulating the rollover of the structure, which demonstrates the importance of using either type, since failure to use them could result in serious damage to passengers.

    Estudio del impacto lateral del autobús urbano con carrocería IMPA para determinar la configuración de la estructura que cumpla con la normativa de la UNECE regulación R095R02
    (Universidad Técnica de Ambato. Facultad de Ingeniería Civil y Mecánica. Carrera de Ingeniería Mecánica, 2017-10) Avilés Ramírez, Robinson Paúl; Arroba Arroba, César Hernán
    The present investigation is based on the study of the lateral impact of the urban bus with IMPA body, based on the Spanish regulations of the UNECE Resolution 95 Revision 02, being a regulation to safeguard the life of the occupants in case of lateral collisions, the same which specifies the test conditions together with the positions to perform the different types of impact. The tests are performed by computational analysis and finite element method, with a dynamic study as the main parameter. For the computational analysis of the structure, three basic points of application of the impact are taken into account as they are: the part of the driver, average and the later, in each test will be made with an adult manikin without arms as specified by the regulations, which will be impacted by a car, of which the superstructure will remain at rest and the car will maintain a constant speed of 50 km / h. The results obtained from the tests show that the superstructure meets the acceptance criteria that were taken into account such as: head, thorax and energy factor (Hourglass), which are within the range of acceptance.
