Abstract
Chassis is an important auto parts,which used in supporting, installation automotive engine and its components, assembly, and forming the overall shape of the car and the engine power acceptable to have a sports car, and ensuring the normal running. With the number of models and increasing truck beam assembly is expected to support the volume of the 2004-2006 average annual growth of 60% average annual sales growth of the community about 30%. In recent years, with the diversification of models, as well as the core engine replacement parts, such as changes in the requirements of the chassis has become increasingly diversified, the beam forming process requirements will increase accordingly. With the rapid development of China's automobile industry, customer demand for personalized, more and more endless variety of beam deformation, the traditional method of processing can not meet those requirements.
In this paper, automotive products longeron process requirements, design the metal bending modulus. Has been designed in accordance with the mold-related data such as size and strength to build the model. In different simulation parameters, such as forming sheet metal bending with different thickness, the virtual velocity, virtual quality, nodes, modules and simulation of bending process of wrinkling and rupture analysis, analysis of the design variables, objective function, constraints, and ultimately a optimal thickness of the bend. Reduce errors in production, saving production costs and material resources to increase production efficiency.
