theories of modularization and parametric 3D model are adopted to design 3D model of Stack Machine module. With the support of Microsoft Access database and the programming language of Visual Basic
the interface between model and data is established. After making the FEM analysis of the structure by COSMOS
a parametric design system has been developed
which may be applicable to manufacture industry of logistics equipments. It has been proved that the design system can improve the design efficiency and quality sharply
