A Study on the Design Method of Passenger Car Type Front Side Member Using Tailor Welded Blanks

Tailor Welded Blanks를 이용한 승용차용 Front Side Member 설계기법 연구

The use of tailor welded blanks(TWB) in automotive applications is increasing due to the potential of weight and cost saving In this study, the front side member of passenger car is developed by typical analysis and crash simulations. According this results, energy absorption and barrier force is very important to control passenger safety and deformation shape. For that purpose, it is most effective to absorb energy more tailor welded blanks front side member than non-twb. The front side member with twb is simulated, in which reduced stamping parts, weight reduction and cost down.
