Crash Simulations of a Racing Kart's Structural Frame Colliding against a Rigid Wall

Crash Simulations of a Racing Kart Frame Model This dataset contains results for several crash simulations of the frame of a racing kart colliding against a rigid wall. 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. 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. 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. Moreover, the source code of the finite element model itself, written for the commercial simulation software LS-DYNA, is included as well.

本数据集收录了赛车卡丁车车架模型在碰撞刚性墙壁过程中的多场撞击模拟结果。墙壁及车架本身均被建模为有限元模型，并采用商业软件LS-DYNA进行实现。LS-DYNA软件包含9314个节点，每个节点拥有3个平动自由度。模拟场景涉及卡丁车与刚性墙壁的碰撞，撞击速度在5至30米每秒之间变化，撞击角度在-45至45度之间，屈服应力在168至758兆帕之间。撞击角度定义为墙壁法线与卡丁车方向之间的夹角，而屈服应力则影响卡丁车材料的有效塑性应力-应变曲线，该曲线与典型钢的曲线相匹配，但根据每次模拟的独特屈服应力进行调整。每场撞击模拟覆盖0.003秒的时间范围，采样间隔为0.3毫秒，每场模拟产生101个样本。共生成128组参数组合，采用Halton序列进行。此外，还包括了为商业仿真软件LS-DYNA编写的有限元模型源代码。内容模型包括LS-DYNA有限元仿真软件的输入文件，包含模型描述；卡丁车数据集则包含模拟结果，包括节点位移和仿真参数，单位为[N,m,s]。
