Study of the structural tests based on stress at the vehicle suspension attach points 2008-36-0201
Time and development cost reduce is nowadays a basic premise of automotive industry. Connected with this, many efforts have been done in the sense of design lighter structures, what involve in gas consumption reduction and improvement of vehicle performance.
The accelerated tests contribute in time and development cost reduction, since the tests are planned in according to have a short time execution so reducing the period of the experimental validation step. The use of fatigue analyze techniques can aid in time reduction of test execution.
The purpose of this work is study, based on stress analysis, the most severe grounds for the vehicle suspension attach points. The severity will be defined in according of the calculated stress through von Mises criterion, using the cumulative damage theory. Then, it hope know the damage caused to the attach points due the ground type and with this, optimize tests necessary to validate these points and reduce the time necessary to the vehicle structural validation.
