Abstract:
Over recent years, demands for fuel-efficient vehicles have increased with the rise of the fuel price and public concerns on environment. Recently, application of lightweight materials is increasing in the automobile industry in order to improve mass reduction and consequently fuel efficiency.On this particular study, with a goal of developing a Lightweight Fixed Steering Column, it was identified an opportunity to replace fixed steering column metallic upper and lower brackets by polymeric material. In order to fulfill NVH, Crash, Durability and Performance requirements, a DFSS methodology has been applied.As a result, It was achieved ∼51% of mass reduction, ∼10% of performance improvement with ∼14% of cost increase.
