Meta-Models application on bumper crash design optimization developed with modeFRONTIER

The challenge of this presentation is the optimization of a bumper during a frontal crash situation. During the optimization six parameters were used in order to optimize the bumper by reducing mass and minimizing force. The optimization comprised three steps that go from geometry design to physical behavior simulation.

Multi-level approaches for optimal system design in railway applications

The focus of this thesis is centered on the optimal design of complex systems. Two main optimization approaches are addressed in this work: the metamodel‐based design optimization and the decomposition‐based complex systems optimal design.

A CAE based procedure to predict the low velocity impact response of a composite CAI specimen

In this case, modeFRONTIER was coupled with an LS-DYNA FE model in order to simulate the impact low velocity impact on composite plate.

Structural Optimization in Early Design Phase @ VOLVO Cars

The presentation examines the structural optimization done in early stages of the design phase.

Parameterization and Multiobjective Optimization

The main goal of this paper is to show the way in which single and multi-objective optimization can be implemented to improve new products. The author found an optimal strategy for model parameterization of a control arm complying with four criteria and parameterized it  performing automatic and manual optimization to verify the criteria to comply with were met. The overall goal is to reduce weight by 10% the control arm while maintaining the stiffness

Predictions - Their relationship to optimization

"Why are we so bad predicting?" Starting from the most striking prediction failures, Ciro Soto wonders about the role of real phenomenon predictions in the engineering analysis and how RSM methods can help reducing the related errors.

Finite element reconstruction of real world aortic injury in near-side lateral automotive crashes with conceptual countermeasures

Traumatic rupture of the aorta (TRA) remains the second most common cause of death associated with motor vehicle crashes after brain injury. On an average, nearly 8,000 people die annually in the United States due to blunt injury to the aorta. It is observed that more than 80% of occupants who suffer an aortic injury die at the scene due to exsanguination into the chest. With the advent of more accurate and established human body finite element (FE) models, FE crash reconstruction methods may become a valuable tool when assessing crash scenarios and occupant injury mechanisms. The current study is divided into five main aims, near side left lateral real world finite element reconstructions, sensitivity study, thresholds for TRA, aorta mechanics in racing crashes and conceptual countermeasures. In the first study eight nearside left lateral impacts, in which a TRA occurred, were reconstructed using a combination of real world crash data reported in the Crash Injury Research and Engineering.

Rear-seat Restraint Optimization Addressing the Different Needs of a Diverse Population

Most rear seats are too long for most children ages 4-17, a design optimization project was undertaken in order to explore the optimum belt and seat configurations for children with a range of body sizes.
