Análisis de los efectos del airbag del conductor de autobús en colisiones frontales mediante simulación

Abstract

The present thesis work was carried out in order to analyze the effects of the airbag produced in interprovincial bus drivers, for which airbags were located in its structure and later simulations of frontal crashes were carried out using the CEPE R94, RMDB regulation. by EURONCAP and NHTSA put into effect from the year 2020. For the initial stage, the interprovincial bus was selected to model the structural contribution elements using CAD software, later ANSYS LS-DYNA RESEARCH was used for the simulation, where the selection of the airbag and its adequate position was taken into account, the dummy Hybrid III that allowed to measure 8 injury criteria established by the R94 regulation, and the barriers for frontal and oblique impacts given by EURONCAP and NHTSA. Once the necessary elements and parameters were entered into the software, the simulations began, which consist of 4 crashes with and without airbags, one frontal and the other with an oblique phase shift of 15 degrees. Once the simulation was completed, the results were compared and interpreted. With the investigation it was concluded that the use of the airbag is harmful during frontal crashes and that they are not important, because they increase the injuries in the driver, this being verified by obtaining results that exceed the limits given by the criteria of injuries in the dummy of the regulation. R94.
