Abstract:

This study aimed to optimally design a parametrically generated bumper geometry under operating conditions. By changing the bumper geometry at the specified boundary conditions, the mass of the structure, strength and critical lifetimewere examined. As the optimization target, it was determined to meet in minimum mass, maximum critical lifetimeand minimize the stress results where is below theyield stress. This study was carried out with the pSeven workflow; CATIA for parametric CAD model, Patran & Nastran for finite element analysis and nCode for calculating critical lifetimewere used.
