Manufacturing information is determined by the country to comprehensively enhance the market competitiveness of China's manufacturing industry during the \. This paper argues that the technical system of digital design technology including product information and design process of digital (CAD) product manufacturing process the digitized (CAP) and the design and manufacture of process digitized (CAM) three components. Considerable progress has been made in the CAD and CAM direction, but is lagging behind in the direction of the CAP, which restricts the development of digital design technology. Virtual design technology is relatively conventional design techniques, the integration of simulation and modeling technology, virtual experiments through simulation and modeling of the manufacturing process of the product, the product manufacturability and manufacturing technology to predict, evaluate and optimize virtual design The technology is one of the product manufacturing process of digital technology (CAP) represents the technology of. In view of the above, combined with the the Combined Brake beam production technology and equipment, finite element technology as a tool, the modular brake beam production technology and equipment for engineering practice and application of virtual design technology. Combined Brake Beam parts - brake beams in hot forming, using the finite element software ANSYS, considering the conduction, radiation, convection factors, especially complex radiating between absorb radiant energy, the whole process of hot forming thermodynamic analysis, to make the temperature drop curve, provides a basis for each station beats, robot action, production technology and production line design. In the process of thermal analysis, innovative use of multiple inheritance modeling method, successfully resolved the splitting of the workpiece lead to unit Grid tear and node separation resulting in finite element method based on the continuum assumption can not simulate such case of problems. This approach provides a reference to solve similar engineering problems. By the finite element structural analysis to determine the the cold assembly installation center pillar kicked program; formation mechanism of the workpiece error, error detection scheme; based on the detection scheme by analyzing the simulation to determine a reasonable school-program. The virtual design practice and the results of the Combined Brake Beam production and production line design made the prediction and evaluation of the role, also confirmed the author on the virtual design technology in digital design technology and even manufacturing information technology system in view of the status and role.
