Design and development of an innovative apparatus for producing a spiral catalyst substrate for catalytic converter
Spiral catalyst substrate is one of the substrate types for catalytic converter and has high geometric surface area. It is to provide support structure in which the washcoat and the catalyst are applied. Currently, an issue of considerable interest in producing the substrate from a thin sheet...

| description | Spiral catalyst substrate is one of the substrate types for catalytic converter and has
high geometric surface area. It is to provide support structure in which the washcoat
and the catalyst are applied. Currently, an issue of considerable interest in producing
the substrate from a thin sheet metal with a thiclmess O.l1mm and using FeCrAI
material has become a trend. Existing patented apparatus overseas use a complicated
system and specific details are scarce. Therefore, this research presents the works in
designing and developing an innovative apparatus based on a systematic approach of
Pahl and Beitz's model of design process. Furthermore, Finite Element Method
(Dynaform) was applied for the forming analysis of a trapezoid cell of corrugation on
a thin sheet metal and spiral shape of corrugated sheet metal. These works provide
the conceptual designs for the apparatus of Corrugated Tool for corrugation process
and Spiral Tool for spiral process. The selected conceptual design was established by
developing a model of the apparatus. A rule of thumb for requiring unloaded
diameter of corrugated sheet metal in spiral shape was derived. Forming Limit
Diagram (FLD) shows that the thin sheet metal was successfully formed without any
cracking and Thiclmess Diagram shows that the thiclmess of the formed thin sheet
metal was in safe thickness. The springback effect that occurs during the sheet metal
in spiral shape was solved using the developed casing. The designed apparatus of
Corrugated Tool and Spiral Tool were fabricated and optimization was performed by
producing the spiral catalyst substrate. The innovative apparatus for producing the
full scale of spiral catalyst substrate were successfully designed and developed. |
