Modelagem, validação e otimização de dispositivos para teste de mecanismos de direção

Abstract

The laboratories of the automotive industry need to test the internal systems of vehicles to check strength and durability. An example is the steering mechanism, which is fixed at a device with high resistance, and subjected to loads of great intensity. These device of fixation generally do not follow a structural analysis criteria, or reduction in weight of structural optimization. As an object of study, have two devices in a laboratory test of steering mechanisms. In this work, devices are subjected to loads and deformations are acquisition experimentally. The devices are modeled in CATIA ® program, and their structural behavior in the computational analysis ANSYS ® program. The experimental data are compared with the theoretical generating a validation of the model. Subsequently the optimization of the devices is made. Finally results are compared, mass and strength optimized model with the actual device.
