文摘
- •
We proposed a novel foam-filled double ellipse (F-DET) tube.
- •
The crashworthiness of the foam-filled double ellipse tube under multiple loading cases was considered.
- •
The design of experiments (DOE) method provided the means to select the sampling points.
- •
The multiobjective particle swarm optimization (MOPSO) algorithm was used to optimize the F-DET tube about the radial rate, wall thickness and foam density.
