摘要	To study the synergistic hierarchical arrangement effect, three hierarchical cubic lattice structures and six kinds of hybrid hierarchical lattice structures are designed based on the synergistic hierarchical arrangement concept. While studying the synergistic hierarchical arrangement effect on the structural protection characteristics, the prediction function of structural properties and the constitutive relation of lattice structures are derived. The structural properties are accurately predicted, and the errors are within 5%. In terms of mechanical properties of lattice structures, 941 hybrid hierarchical lattice structure, similar to the hybrid hierarchical arrangement inside the femur, presents the best mechanical behavior, followed by 194 and 419 hybrid hierarchical lattice structure. The bearing capacity, specific energy absorption, and energy absorption of 941 are more than 100% of those of other hierarchical or synergistic hybrid hierarchical lattice structures. The results show that the hierarchical and synergistic hybrid hierarchical lattice structure can effectively improve the mechanical properties of the lattice structure in different directions, especially the femur-like synergistic hybrid hierarchical structure. To better determine the excellent performance of the hybrid hierarchical structure, combined with the car seat, the per-formance of the hybrid hierarchical structure is further studied. Ideas are provided for the subsequent application of energy-absorbing engineering.
