Currently, studies are being developed by automobile engineers about the energy required by the client during the closing door of the car. This paper proposes an analysis of A segment vehicle, four doors, in order to evaluate the influence of each component of the door/body responsible for closing the side doors. Tests will be carried out to demonstrate exactly the contribution of the door sealing, exhaust air valve and the inner cabin air pressure effect, door link, hinges and latch, plus the actual weight of the door during the closing. The results show which are the door/body components most responsible for car door closing movement energy increase and still, where to direct efforts to provide greater comfort for customers.

Currently the durability test of FIAT vehicles powertrain suspension system is performed in pattern roads that reproduces conditions which the vehicle is submitted by costumer during product life cycle. The test done in these roads is time consuming and expensive. Experimental Engineers, for quite some time, have endeavored in doing automotive components fatigue tests in the lab. These environments provide more controlled test conditions and enable a less time consuming test. This work analyzes, over one of the three powertrain system attachment points of a passenger vehicle, differences that are found between a test performed in pattern roads and a test performed in a 6DOF road simulator. As conclusion, presents alternatives to perform the test of these components in lab using a 6DOF road simulator.
