Abstract:In order to carry out certain research of design and development in millipede forming equipment，the virtual prototyping technology was used in the design and the development of the product． Parts of the equipment were created in 3D modeling software of SolidWorks ，and the three-dimensional model of the equipment was completed using the bottom-up virtual assembly model． The wellestablished models can be imported into multi-body dynamics simulation software of ADAMS，and the millipede forming equipment
transmission was built by using the software ADAMS，then the virtual prototype can be analyzed by the kinematic simulation． The simulation results which can be seen in ADAMS demonstrated the rationality and reliability of the mechanism design．
