Outdoor objective evaluations form an important part of both tire and vehicle design process since they validate the design parameters through actual tests and can provide insight into the functional performances associated with the vehicle. Even with the industry focused towards developing simulation models, their need cannot be completely eliminated as they form the basis for approving the performance predictions of any newly developed model. An objective test was conducted to measure the ABS performance as part of validation of a tire simulation design tool. A sample vehicle and a set of tires were used to perform the tests- on a road with known profile. These specific vehicle and tire sets were selected due to the availability of the vehicle parameters, tire parameters and the ABS control logic. A test matrix was generated based on the validation requirements.

It is repeatedly proved that any minor change in the parameters involved in the test set up of BIW Bending and Torsion Stiffness evaluation changes the final test results significantly. The primary aim of the Physical Stiffness Tests, in the development stage of an Automotive Body is to ensure CAE co-relation. The setup for the physical test must therefore be designed such that the constraints match exactly with the ones in CAE. This will avoid any issues of correlating the test conditions. Any deviations in the test results between the two can then be studied separately. At first, this paper analytically deals with the mounting points that should be used on the various vehicle body types based on the different types of suspensions they employ. Based on the theoretical conditions, a practical test set-up has been derived for testing the Bending Stiffness and the Torsion Stiffness separately.
