Abstract: Frame structure of embedded system for quick design of typical parts and components (TPDS) running on several popular3D CAD platforms is presented.Machine parts are built up from user defined features (UDF) according to templates and stored in specially implemented databases.Design and verification packages are provided for seven classes of machine parts,namely gears.shafts,springs, worms and gears,rolling bearings,screw fasteners,and keys.Functions for generating various templates parametric reconstruction,design navigation and automatic assembly are available.On the whole TPDS system is a versatile,rapid and intelligent integrated system from designing,analysis to3D modeling and automatic assembling.
