Análisis biomecánico mediante simulación computacional de las lesiones que puede sufrir un piloto en un GO KART de competencias interuniversitarias caso de estudio: impactos frontales

Abstract

The technological development in the design of go-kart structures has not yet been adequately explored in the country, and the few investigations that exist do not offer conclusive results on the safety of the drivers. Furthermore, the absence of structural and biomechanical analyses provides inaccurate data in impact situations. Therefore, the objective of the research was to analyze the injuries of the hybrid III male dummy during frontal impacts, kart-rigid wall, kart-front kart, and kart-rear kart to verify compliance with the acceptance criteria according to the CEPE R94 regulation using the finite element method. For this, the structure of the kart was modeled through the SOLIDWORKS design software, and through the LS-DYNA program, the dummy specialized in collecting injury produced in the human body data was obtained. The meshing of the Shell and Solid type elements in 2 dimensions was carried out, which allows reaching a mesh that meets the JACOBIANO criterion, and the impacts of the simulations were carried out at a speed of 50 km/h. The results obtained allowed us to know, for each case, the head injury criteria (HIC), the thoracic severity index (CSI), neck injuries, and femur injuries. Verifying that for the first case, there are serious injuries, while for the second case, there are minor injuries, and finally, in the third case, it is feasible that there are no injuries. In this context, it is concluded that there are minor to severe injuries to the pilot, so it is recommended that the driver wear a seat belt with at least two anchor points
