Study on Modular Design Based on the Theory of Life Cycle

摘要

Based on the analysis of the traditional automobile design mode, the paper puts forward that the concept of changing from simple function design to product life cycle design. Moreover, the life cycle design theory based on modular design can better serve the subsequent links of automobile manufacturing in the design stage. Combined with the wide application of CAD/CAE technology in automobile design, the concept of automobile modular design based on life cycle theory is explored. Automatic Mechanical System Dynamics Analysis Software (ADAMS) can realize the functions of parametric modeling, design and analysis. In addition, parametric simulation analysis can analyze the influence of design parameters on vehicle performance. By taking the vehicle model created in ADAMS/Car and Vehicle handling analysis as an example, the combination of various module types and relevant parameters can quickly realize the module variant and model expansion. The modular design of automobile based on life cycle theory can analyze the most dangerous operation conditions, obtain the optimal prototype model and the best parameter setting, shorten the design cycle, reduce development cost and improve the product performance. This kind of automobile design mode, which integrates advanced theory, mature design means and excellent computer software will become the future development direction and trend of automobile design.
