Numerical Calculation of Passive Tubular Energy-absorbing Buffer Device

In recent years, there has been a growing emphasis on developing effective impact protection systems to enhance safety and minimize damage in various industries. This study focuses on investigating the properties of aluminum alloy tubular buffers using data analysis technology, with particular attention given to key performance indicators such as law of energy absorption value and crushing force fluctuation. The data analysis results reveal significant elastic-plastic deformation within the aluminum alloy tube, with the region in contact with the press head experiencing the highest stress. Notably, the stress distribution along the Y-axis profile demonstrates a relatively uniform pattern. Furthermore, statistical analysis of the crushing force exhibits periodic fluctuations characterized by a serrated distribution pattern. Abundant data provide valuable insights into the behavior and performance of aluminum alloy tubular buffers, underscoring their potential applications in impact protection systems. The outcomes contribute to the advancement of knowledge in this field, facilitating the optimization of buffer design and enhancing safety across diverse industries.
