Production and Assembly of Car Body Fifth Door with Use of Dual-Phase Steel HCT500X

Abstract

Abstract Due to environmental concerns and safety standards in the automotive industry, the development of durable and lightweight cars has become an important topic. Lowering the weight of the car body has become a crucial topic for all manufacturers, regardless of using combustion, electric or hydrogen engines. To fulfil this need a material with a higher strength to weight ratio must be used. Dual-phase steels seem to provide the right combination of mechanical properties for the production of particular car body panels. The goal of this research is to develop robust production of the fifth door part from HCT500X steel (DP500). The goal of this article is also to depict the forming of the selected part and the fifth door assembly for 4th generation of ŠKODA Octavia. Numerical simulation is accomplished within the AutoForm Forming R8 and AutoForm Assembly R9 solutions. Different aspects influencing numerical simulation accuracy and topics relevant to the production chain are discussed in this article. This research is carried out in cooperation with ŠKODA AUTO, a.s.
