| Popis: | 101 Designing for the vehicle safety is intent to reduce the severity of injury to passengers or to the vehicles. The study uses injury index of dummy as a design criteria to improve the vehicle safety. Among all the crashes, the frontal impact has one of the highest occurrence rates; therefore, the frontal impact is used as the major functional performance considered for the design improvements. In the study, dummy Hybrid III is used. The analysis results are compared with those in the literature to verify the accuracy of the analysis model, and then the analysis model is further used for optimization to improve the crashworthiness of the vehicle using injury index of the dummy. The results from the study show the thickness and shape of the front rail have great effect on the vehicle crashworthiness. After the optimization, the dummy head injury index is reduced more than 10%, and the injury scale is improved from level 1 to a smaller and better scale of level 0. |
