Abstract:	Ti6Al4V ordered porous sandwich structure based on Triply Periodic Minimal Surface (TPMS) has the advantages of light weight, high strength and good designability, and has broad application prospects in aerospace, biomedicine and other fields, but its sound insulation performance has not been fully studied. Based on this, the Ti6Al4V ordered porous Diamond sandwich structure is designed by TPMS implicit function method, and the effects of cell layer number, panel thickness and volume fraction on its sound insulation performance are studied. The results show that the volume fraction has the greatest effect on the sound insulation performance of titanium alloy ordered porous Diamond sandwich structure, and the cell layer number has the smallest effect on the panel thickness. Increasing the volume fraction and adjusting the number of cell layers can effectively improve the sound insulation performance of the sandwich structure. The sound insulation performance of Diamond sandwich structure is studied on the basis of its light weight and high strength, and the versatility of Ti6Al4V ordered porous sandwich structure is extended.
