Abstract:
The tubular bumper structures, which are a new manufacturing method based on the principle of hot-stamping, structural design, theory of inventive solving problems and test evaluation, represent a new paradigm in vehicle bumper frame construction. This study focused on improvement of stress resistance of steel pipes through advances in materials science and hot-stamping techniques, verification of the formation part and proposed structure by manufacture examination, performance to improve by computer analysis and new vehicle testing methods. As a result of the application, this paper quantifies increases in strength, optimization of structural design and possibility of production for vehicle body.
