Modal Analysis of a Composite Monocoque

Created using ANSYS 1314.0

Problem Specification

One of the important measure in race car design is torsional stiffness. To obtain that specification, a twist test must be performed on the chassis. Here is a simplified version of race car chassis with a composite monocoque and two front suspension links. To simulate a twist test, the back of the monocoque will be fixed while coupling will be applied to the end of the two front suspensions. The .igs file for the geometry can be downloaded here: monocoque.IGS.
