Abstract：The impact force curve fluctuates greatly when the collision occurs in the energy-absorbing device, and there is a problem that the impact force cannot be dissipated smoothly. Through quasi-static compression test and finite element simulation model, the mechanical characteristics of the open-hole square tube under axial load were studied in terms of the number of layers of open holes, the number of open holes per layer and the size of open holes, and the results show that changing the center distance of open holes can make the phase separation of the load-displacement curve of the square tube in axial compression. On this basis, a study on the combination of open-hole multi-tubes was conducted, and the results show that the combination of common square tubes and open-hole square tubes with different open-hole center distances can effectively alleviate the force fluctuation and reduce the peak load. Finally, an open-hole multi-tube combined energy absorption structure with good energy absorption characteristics and flat load-displacement curve was obtained. Compared with the traditional combined energy absorption structure without open holes, the compression force efficiency CFE of this structure increases to 48.36%, and the initial peak load PCF and load fluctuation ULC are reduced by 10.28% and 33.33%, respectively.
