Abstract
This paper exposes how the torsional stiffness of a formula SAE student's (FSAE) frame can be evaluated by bench testing and comparing the results from two differente models of testing. The team FGR UnB provides his chassis for the test with two different types of clamping to observe its consequences. The final results did not allow to validate the computational model, however, permits to observe important factors along the bench testing and corroborate some patterns of the results. These modeling setups were analyzed and tested on the same tubular chassis: the first aims to be as similar as possible to the real suspension anchor points and the second is simplest than first and is analogous to models used since 1990's decade, to obtain a reasonable chassis' stiffness results that can be useful to some situations
