Study on the Energy Absorption Characteristics of the Embedded Plate Hexagonal Corrugated Energy-Absorbing Component
A novel hexagonal corrugated energy-absorbing element with an embedded tube plate design was proposed to address the issues of insufficient load-bearing capacity and stability in existing energy-absorbing elements used in impact ground pressure support.A model of the novel energy-absorbing element was established and compared with an existing square energy-absorbing element to analyze their mechanical properties.The results showed that,with the same wall thickness,the new embedded tube plate hexagonal corrugated element exhibited significant improvements in peak compressive load,average compressive load,and total energy absorption,while reducing the load buffer index by 14.5%.With the height of the novel energy-absorbing element kept constant,smaller hexagonal tube sizes within the element led to larger peak compressive load,average compressive load,and total energy absorption.However,a side length of 60 mm resulted in the lowest load buffer index.Similarly,with the height of the novel energy-absorbing element kept constant,thicker walls resulted in larger peak compressive load,average compressive load,and total energy absorption,but a wall thickness of 8 mm led to the lowest load buffer index.By analyzing different sizes and wall thicknesses,it was concluded that a side length of 60 mm and wall thickness of 8 mm achieved optimal energy absorption,providing new insights for the study of energy-absorbing elements.
