Structural and Multidisciplinary Modeling for Sensitivity based Optimization Workflows
In this seminar we present state of the art multiphysics modeling and optimization of CAE workflow for the design of transport systems. Focus is on the transformation from fossil based mobility to sustainable automotive systems as electric vehicles.
Invitation by IDA Mathematics to seminar on CAE workflows and mathematical modelling in industry with focus on transport and sustainability by Technical Director Claus B.W. Pedersen, Dassault Systèmes, Hamburg, Germany.
Due to sustainability, the Transport and Mobility (T&M) sector has started a transformation from conventional Fossil based systems to Electric Vehicles (EVs). Thus, we suggest applying CAE workflows including structural and multidisciplinary modeling and non-parametric optimization approaches based upon adjoint sensitivities for addressing the challenges for deriving new and improved designs. Initially, we show the mass minimization of a suspension component considering stiffness, strength and dynamic properties. The applied End-to-End optimization workflow includes automated CAD reconstruction, concept variants for manufacturing constraints and additive manufacturing verification using a coupled thermal-stress process simulation considering continuously evolving convection and radiation surfaces during the manufacturing process. Secondly, we construct a parametric skateboard shell model of the EV including the battery simulations applied to crash scenarios. Structural models are also applied to non-parametric crashworthiness bead and sizing optimization of the sheets for minimizing intrusions and head accelerations. Additionally, strength optimization is tackled using semi analytic adjoint sensitivity analysis for non-proportional fatigue damage.
To conclude, we apply multiphysics modeling for optimizing the electrical machines of the EV drive train system having a major impact on the electrical machine performance and the overall comfort of the EVs. Consequently, the present implemented modeling and optimization technologies can drive the T&M designs of the sustainable transformation. Additionally, it will also be emphasized how the present technologies can be applied in industrial design workflows for many other sectors, i.e., life science, aerospace, renewable energy and high tech
