Design and Analysis of a Conceptual Modular Aluminum Spaceframe Platform 2005-01-1029
This paper documents the design and verification process of a modular spaceframe platform for SUV, hatchback, sedan and station wagon conducted at the Institute for Advanced Vehicle Systems (IAVS) of the University of Michigan-Dearborn. The goal of the project was to show the feasibility of a cost effective family of vehicles for low volume markets and reduce the body structure mass while meeting current industry and federal standards.
For low volume markets the cost of using spaceframe construction is more economical compared to the traditional unibody construction. Cost is further reduced because a family of low volume vehicles would share a lot of common parts. Also, spaceframes can use extruded sections joint by cast nodes, which are both inexpensive.
The results discussed in this paper show the CAE work done on beam models for a family of vehicles including, sedan, station wagon, hatchback and SUV. It also includes detailed CAE analysis of the sedan and SUV variants, which includes crash analysis.
