So the mould design of the restored model includes the two study aspects of structural mould and art mould. In this paper, some new results obtained from the relevant historical literatures and archaeological study are reviewed first, and then the three kinds of tube-, bell-, and egg-shaped moulds designed in existing models are discussed briefly. Based on the newly restored model turned out by the research group of China Earthquake Administration and State Cultural Relics Bureau, in addition to analyzing the corresponding design restoration of basic shape, the position of upper hanging point, adjusting structure and instrumental stability relating to structural mould, the paper also introduces the design idea, cultural succession and art expression relating to art mould. The purpose of design restoration of Zhang Heng's seismometer is for better displaying Zhang Heng's great historical contribution to the world. [ABSTRACT FROM AUTHOR]
