rigidity, weight, and operator ergonomics. The number one priority in the chassis design was driver safety. With the help of the 2009 Baja SAE® Competition Rules and
Finite Element Analysis (FEA), design assurance was able to take place.
ABSTRACT
The Society of Automotive Engineers sponsors competitions that challenge aspiring engineers to create a miniature off-road vehicle. The SAE Mini Baja® competition objective is to design and fabricate a prototype vehicle that could be manufactured for consumer sale. The University of Wisconsin Platteville
(UWP) has accepted the challenge to participate in this competition. An aspect of this competition is to compose a design documentation package that creates an overview of the vehicle’s construction elements. The
UWP Mini Baja® team has created this report to describe their design.
DESIGN
The main components of the frame are broken into two groups: the chassis and the roll cage. The roll cage is made up of the RRH, RHO, FBM, LC. The chassis is made up of LBD, LFS, SIM, FAB, and FLC (See page
11, the Acronym list, for member clarification).
Material
1020 DOM was chosen for the roll cage because of its high toughness and ductility. A very tough material is important in a roll cage because in the event of impact, such as a rollover, the roll cage needs to absorb as much energy as possible to prevent the roll cage material from fracturing. 4130 was chosen for the chassis because it has structural properties that provide a low weight to strength ratio. 4130 is a chromium molybdenum alloy steel that has controllable properties.
Attributes to 4130 include
