Abstract—With the goal of reduced weight, free-size finite element based optimization with constraints on
stresses and deflection of a car seat backrest manufactured from low strength steel plate is
performed using ANSYS software. In the free-size optimization, sheet metal thickness in a finite
element plate of the backrest is design variables with stress and deflection limits as the
constraints, with an objective to minimize mass. Using the results from the free-size optimization
and a minimum draw-able sheet metal thickness, a final design is derived which obtains a total
mass reduction. To verify the functional performance of the final design, the final optimized seat
backrest is performed using the ANSYS software package. Results from the analysis provide
an accurate prediction of the material yielding and load distribution on the backrest plate provide
factor of safety estimates on yield and ultimate strength.
