| Abstract [eng] |
The full scaled model of the impact attenuator would be expansive, so a scaled model of the impact attenuator was used to perform the experiments. The honeycomb and foam materials were tested using a UTM machine in out of plane behaviour i.e. in compression. In the compression test of foam and honeycomb materials of same dimensions it was found that honeycomb absorbed more energy than foam. In the next step the honeycomb sandwich with glass fibre was tested on the high impact penetration machine and energy absorbed by it was observed. The roll cage of a student formula car was also test under front impact loading to understand the extend till which energy absorption should be done to safe guard the occupants without effectively increasing the weight of the vehicle by using more thickness of tubes for roll cage, using more stronger material or by adding more bracing members to the roll cage. The results obtained from experimental data were used as an input to model the material in the FEM package of the ANSYS. Using ANSYS the full scaled model of the impact attenuator was also analysed. |
