วัตถุประสงค์
:
The goal of this project is two folds. First, the floating caliper disk brake, commonly used in a front brake system, is modeled with respect to self-excited vibrations or squeal as either low or high degree of freedom models. The mathematical-mechanical models should consider essential features of the floating caliper disk brake system and also be able to predict disk brake squeal. Second and foremost, the models are used to eliminate brake squeal in the floating caliper disk brake by active control using piezoceramic elements. The model- based real time active control of squeal requires low degree of freedom models, so that the control laws can be implemented in real time on present day computers. This optimal control will also be applied to the higher-degree of freedom model to check and verify the controller. Furthermore, the models with this optimal controller can be tested to eliminate brake squeal using a numerical simulation or a test rig which was developed and built in the laboratory in Darmstadt (Germany).
