Abstract.
Another thing to be emphasized is that although the design method to the model has limitations in practical engineering, it has reference to engineering practice.
The competition test shows that the structure has good performance in collision, which means the design method of the structure model is of thinking novel, simple principle, own certain technical superiority and innovation, has reference to engineering practice.
