摘要
The earthquake is a natural disaster which is irresistible and hard to forecast. In the earthquakes, the helmets play an important role in protecting the head of people. The traditional helmets have some disadvantages of storability. Even very few foldable helmets have been designed, the price of them are expensive. In order to overcome these disadvantages, and from the prospect of application to origami-engineering, we challenged to invent a foldable helmet based on origami structures. We designed the helmet using the origami structures of accordion cover origami structure/honeycomb origami structure and the low-priced energy absorption material of corrugated cardboard. Because the designed origami helmet is necessary to satisfy the safety performance, the impact FEM analyses are done to investigate the mechanical characteristics of the designed origami helmets. And the experiments are also done to confirm the safety performance of the designed helmets. Finally, the numerical analysis results are compared with the experimental results.
