Abstract
ABSTRACT
The platform is the basic automotive body structure. It is on this platform that engine
and other components are attached. It is made by stamping of sheet metal. The main
parts are the front and rear. Backbone made of stronger material is used to strengthen
the platform. It is located in the central portion of the platform. For natural gas vehicle, a
gas tank is placed underneath the backbone. The backbone is designed for high
stiffness and ribs are used. The ribs may cause tearing during stamping. The objective
of this paper is to determine the number of ribs that give high stiffness of the backbone
without causing defect during stamping. Finite element is used. The backbone with 3,
4 and 5 ribs was investigated. It was found that backbone with 3 ribs is sufficient for no
failure during stamping. Backbone with 5 ribs shows through thickness crack during
stamping.
