Abstract: |
<b>Crash Simulations of a Racing Kart Frame Model</b> <br><br> This dataset contains results for several crash simulations of the frame of a racing kart colliding against a rigid wall. <br><br> The wall and the frame itself are modeled as finite element models, implemented in the commercial software tool LS-Dyna. The latter comprises 9314 nodes, each possessing 3 translational degrees of freedom. The simulated scenario involves the kart colliding against a rigid wall, with the impact speed varying between 5 and 30 m/s, the impact angle between -45 and 45 degrees and the yield stress between 168 and 758 MPa. <br><br> The impact angle is the angle between the wall normal and the orientation of the kart, while the yield stress influences the effective plastic stress-strain curve of the kart material. This curve matches that of typical steel, but is adjusted based on the unique yield stress of each simulation.<br> Each crash simulation covers a time span of 0.003 seconds with a sampling interval of 0.3 milliseconds, resulting in 101 samples per simulation. A total of 128 parameter combinations were generated with Halton sequences. <br><br> Moreover, the source code of the finite element model itself, written for the commercial simulation software LS-DYNA, is included as well. <br><br> <b>Content</b> <br> <ol> <li>Model<br> * input files for the FE simulation software LS-DYNA containing the model description<br></li> <li>Kart Dataset<br> * simulation results containing the node displacements and simulation parameters. The units are [N,m,s].<br></li> </ol> |
