Research on the center of mass calculation method for dynamic tilting of terracotta warriors from the mausoleum of Emperor Qin Shihuang

Research on the Terracotta Warriors from Qin Shi Huang's mausoleum reveals that the right leg and right side of the waist bear significant stress during dynamic tilting, highlighting critical areas for support in restoration. The study introduces an advanced method combining 3D laser scanning with an improved Moller-Trumbore algorithm to digitally reconstruct internal structures of fragmented warriors. By analyzing thickness data and calculating the center of mass using voxel and tetrahedral methods, it demonstrates that the voxel approach offers higher precision. Stability assessments further emphasize the need for targeted reinforcement in these high-stress regions to ensure artifact safety.
