Modal Analysis of a Composite Monocoque
Created using ANSYS 14.0
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 chassis. The figure below shows a simplified version of a 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 tot he to the end of the two front suspension. the .igs file for the geometry can be monocoque.IGSsuspensions.

One of the beauty of composite material is to customize the ply lay-ups to achieve optimum proeperties properties according to the needs. It is often the case where different ply lay-ups are used at different monocoque regions for their sepecific specific needs. This excise have exercise has 4 different regions as shown in the above diagram below:
Detail of . Details of the composite layup will be explain explained during the excercise.
Calculate the Torsional Stiffness
exercise.
In this module, we will calculate torsional displacement with the use of ANSYS PrepPost and ANSYS Mechanical. Torsional stiffness will then be calculated using the following equations:Ansys gives tengential displacement values for torsional displacement, and here are the equations to calculate the torsional stiffness
