Through virtual dynamic simulations it is possible to gain quality, safety, reduce cost and development time. Eliminating prototypes components to avoid future problems with package and early degradation of automotive components. This article has the objective validate the simulation methodology linked with flexible tube and hoses that are under engine displacement action to increase the confidence level of the design. The methodology validation consists in compare scanned physical model and virtual simulation models. Using Simcenter 3D Flexible Pipe software as study base. As input parameters it was used geometrical, physical, and chemical data for the virtual model. Finally, the environment can apply the dynamic movement of the powertrain set in the validation of the package and the evaluated component.

Nowadays the automotive market is reducing product development time and launching more technological vehicles, always focusing on having even more safety with better customer experience which generates big competitiveness and requires more accurate and faster development, the virtual simulations make it possible to meet this new reality with a high confidence level. This work comprises the validation of a methodology to analyze the design confidence level for flexibles associated with suspension kinematics. To validate the methodology, the scanned physical model was compared with the virtual simulations using the Simcenter 3D Flexible Pipe software. As inputs data for simulation, it is used geometrical, physical, and chemical information. Through the suspension kinematics study was establish possible movement situations to obtain the flexibles deformations attending to all suspension positions.

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.

Through computational dynamic simulations is possible to achieve high reliability index in the development of automotive components, thus reducing the time and component cost can generate significant levels of competitiveness and quality. This work suggests the validation of a methodology for simulation, able to predict and quantify the best design of the parking brake cable that although it is flexible, has in its structure composite elements of different mechanical properties. Known difficulty of mathematically predict nonlinear relationships deformation under forces and moments effect was first established, studies based on experimental measurements serve as input parameters for simulating the dynamic behavior of the flexible cable. With the aid of motion making use of NX9 CAD software, it was prepared the dynamic movement that the leaf spring suspension system does.
