Through dynamic computational simulations it is possible to achieve a high reliability index in the development of automotive components, thus reducing the time and cost of the component can generate considerable levels of competitiveness and quality.

This work suggests the validation of a methodology to create the virtual routes to find the best design of the flexible components influenced by force of gravity, thermal expansion or even the static balance between the anchor points and used to be designed and installed in the vehicle always in the nominal condition which in many cases diverge from the physical.

With the difficulty of predicting mathematically the nonlinear relations of deformation and motion under the effect of forces and moments, we use the NX9 software in the creation of the dynamic movement motion to the motor and transmission assembly imposes on the flexible components through a routine mapped by Cartesian coordinates, simulating the characteristic movements of the vehicle in normal working situations.

Using the software IPS - Industrial Path Solution, for the construction of the flexible model to be simulated, the mechanical and geometrical properties were assigned for each component, as well as its static deformation experimentally captured, in order to obtain the real deformations in a steady state, making the virtual static model accurately represent the experimental model validating its effectiveness.

Finally, it is established to the model the dynamic routine of some flexible components to make a comparison of the efficiency in the elaboration of routes using the installation by the software IPS meeting the requirements of package, avoiding unwanted dynamic interferences and the early degradation of the flexible element.
