Optimization of the Production Process of an A-Pillar using a Differential Thickness Profile Approach via FEA

Abstract

Energy efficiency of car body structures includes, in addition to the obvious aspect of fuel consumption, an ultra-high level of passenger safety. However, with traditional manufacturing processes, an acceptable level of passenger safety results in an increased car body weight. The realization of ultra-high strength properties and, at the same time, improved structural weight could be achieved through different tailoring routes such as: Tailor-Rolling, Tailor-Welding, and differential thermomechanical processes. In this technological context, an FE model is developed for the improvement of tailored-rolled technology through which an optimization of state of the art thickness can be realized by using different high-strength materials in the proposed FE model of an existing A-Pillar geometry.

Study of Transition Areas in Press-Hardened Steels in a Combined Tool for Hot and Cold Forming

“…It is related to the increase in mechanical properties and the reduction of vehicle weight. UHSS are used in the hot stamping process for parts such as side impact reinforcement beams, A-pillars, B-pillars, and bumpers [1,2]. The entire automotive industry is trying to achieve as much sustainability as possible.…”
