Abstract - The focus of studying energy-absorbing
light weight and high energy absorption efficiency. Strict vehicle safety standards force engineers to have strong suction power to avoid affecting the entire weight of the vehicle. Many studies have been published on the study of energy absorption in metallic tubular thin-walled structures.
structures is to analyze their behavior under impact and compression. Impact characteristics are influenced by geometric factors, which also apply to dynamic loading scenarios. Peak crush load, denoted by Pmax, represents the maximum axial load experienced during compression, usually at the beginning. The magnitude and occurrence of Pmax can be altered by adding holes. The objective of the finite element analysis performed using ANSYS 15.0 with the tool EXPLICIT DYNAMICS is to determine the energy absorption of two types of tubes and compare their effectiveness in absorbing energy smoothly and efficiently. By analysing the impact loading, the solution obtained from the ANSYS test can provide insights into the energy-absorbing capabilities of the structures being tested. Key word energy-absorbing structures, impact analysis, compression, geometric factors, dynamic loading, peak crush load, Pmax, finite element analysis, ANSYS , EXPLICIT DYNAMICS, energy absorption, tubes, smooth deformation.
These studies can be classified as follows: (1) investigates the effect of different geometries and configurations. (2) investigates the effect of foam. Extensive work has been done to investigate different geometric modifications and configurations of thick tubes designed to improve energy absorption in thin tubes. Most of the work published in this area focuses on simple tubular structures visible from the fabrication process. One of these modifications is the splitting of thin walls into simple extruded multicellular profiles that can be partially or completely tubular. Tang et al. investigated the energy absorption properties of multicellular cylindrical tubes and found that different cell geometries improve energy absorption.

1. INTRODUCTION
Other studies on various cell geometries have investigated the effect of thin-walled tubes with different cross sections on energy absorption. Changing the thickness of the tubular structure is another geometric change researchers are investigating to improve energy absorption and reduce weight. Similarly, the effect of varying the thickness of various tubular structures was investigated. Custom-made tubular structures have also been studied as potential energy absorbers with different thicknesses. Expanded metal tubing is another method researchers use to improve energy absorption and reduce weight in thin layers.
As the world population grows, the demand for new cars increases from year to year. According to the International Energy Agency, by 2035 the number of cars will reach 1.7 billion. As the number of vehicles in traffic increases, the number of accidents also increases. According to the World Health Organization (WHO), the total number of deaths in railroads is still incredibly high at 1.2 million per year. People living in cars make up about 50% of this figure. Automotive engineers play an important role in the design of cars to solve this problem by providing maximum safety for passengers. This can be done through safety measures, in which the structure of the car is designed to provide greater protection and safety in the event of an accident.
Other researchers investigated the effect of polygonal tubular structures on energy absorption, while others investigated the energy of double pipes and nested.
The first car structure responsible for absorbing the collision energy in a frontal collision are the front rails, also called the side rails (see Figure 1). Side members are thin-walled hollow tubular structures of rectangular or square crosssection that dissipate energy loss from plastic deformation. Thin-walled systems are frequently used in collision avoidance and energy absorption applications due to their
