Methods to Determine Torsion Stiffness in an Automotive Chassis

Steven Tebby, Ebrahim Esmailzadeh and Ahmad Barari, University of Ontario Institute of Technology

Abstract. This paper reviews three different approaches to determine the torsion stiffness of an automotive chassis and presents a Finite Element Analysis based method to estimate a vehicle’s torsion stiffness. As a case study, a typical sedan model is analyzed and the implementation of the presented methodology is demonstrated. Also presented is a justification of assuming linear torsion stiffness when analyzing the angle of twist. The presented methodology can be utilized in various aspects of vehicle structural design.

Keywords: finite element analysis, automotive, structure.
