摘要：
The periodic lattice structure has obvious advantages in lightweight and multi-functional design. With the development of manufacturing technology, especially the development of selective laser melting, the periodic lattice structure has been more extensively used, and attracts more attention in studying its structural behavior. According to the characteristics of periodic lattice structure, ABAQUS is used to establish its geometric model, and the mechanical properties are simulated and analyzed under compression. Considering three kinds of cantilever beams with solid, periodic lattice and rubber-filled periodic lattice as examples, and comparing with the theoretical results of modal frequencies, the simulation method of the periodic lattice structure is improved. The simulation analysis method is used to analyze the change of mechanical parameters and the change of the damping characteristics of the three types of cantilever beams caused by the dimension difference in different directions. The simulation results can provide a basis for the performance test of the periodic lattice structure and provide a reference for the design of the periodic lattice structure which meets the performance requirements. © 2022, Chinese Society of Astronautics.
