[Case Study] Front Beam Shape Optimization by FIAT

Introduction of a case where automatic exploration of the optimal shape for the chassis part of a vehicle was achieved!

We would like to introduce a case study from FIAT, where our "modeFRONTIER" is applied to optimize the shape of the chassis of vehicles. By using material properties and dimensions as design variables, we are exploring designs that maintain energy absorption rates during collisions while being lightweight. However, applying collision phenomenon simulations to automated exploration calculations was burdensome, so we first simulated 90 designs using a Latin hypercube method with simulation tools. Based on the results obtained, we generated a response surface and applied the approximation function as a virtual solver to automatically search for the optimal solution. [Case Study] ■ Software Used: modeFRONTIER, MSC.Nastran, Raddioss ■ Objective: To explore lightweight designs that maintain energy absorption rates during collisions ■ Challenge: High computational load for applying collision phenomenon simulations to automated exploration calculations ■ Methodology - Simulated 90 designs using a simulation tool with the Latin hypercube method - Generated a response surface - Applied the approximation function as a virtual solver ■ Result: Achieved automatic exploration of the optimal solution *For more details, please refer to the external link or feel free to contact us.
