Vehicle-related accidents are a significant problem worldwide and they do indeed lead to a substantial economic loss for society. It is well known that, as with all other impact types (except the low speed crash), the crash of a rapidly moving vehicle on a straight road occurs in a short period of time. It is desired that the damage on the vehicle will be at a minimum level during this time.. One of the most important parts in the design of vehicle structures is energy absorbing profiles. In the design and testing of energy absorbing profiles, it is required to provide the highest level of protection during an accident. Various types of energy absorbers have been investigated in recent years to reduce the damage caused by accidents in vehicles. Another important trend in the automotive industry in this area is the use of different structures, such as bio-inspired geometric cross section, as energy absorbers in automobiles. In this study, three different bio-inspired structures were designed (1M, 2M and 3M) inspired by the structure of the dandelion to improve the energy absorption ability of hybrid tubes. All models were deformed under the same conditions. In the comparison between hybrid tubes and conventional hollow circular tubes (0M), it was determined that the crushing force efficiency of the 3M model increased by 8.63% and the energy absorption capacity increased by 22.64%. It can be seen that the conventional hollow circular tubes (13.28 kj/kg) have the highest energy absorption capacity in all hybrid these tubes.
