Since tests only provide measurements at sensors, it is interesting to use models to estimate the response at all degree of freedom, correct measurement errors and possibly allow updating of model parameters. The paper gives an integrated perspective on methods developed by the control and structural dynamics communities and in particular methods seeking a trade-off between test and model error. The case of a measured brake squeal limit cycle is used to illustrate implementation details found to be important.

Communication avec acteMARTIN, Guillaume; BALMES, Etienne; VERMOT DES ROCHES, Guillaume; CHANCELIER, Thierry (2015)To be confident in the prediction capability of a model, verification and validation steps are classically performed. Verification checks that the model is properly solved. Since the model used are fairly standard, this ...

Communication avec acteMARTIN, Guillaume; BALMES, Etienne; VERMOT DES ROCHES, Guillaume; CHANCELIER, Thierry (2016)Squeal occurrences are quite common in brakes in production and involve coupling of modes. Detailed understanding of vibration patterns typically requires FEM models updated using test results. The process used at Chassis ...

Communication avec acteMARTIN, Guillaume; VERMOT DES ROCHES, Guillaume; BALMES, Etienne; CHANCELIER, Thierry (2019)In brake FEM, model updating is often needed to improve the model accuracy and well describe problematic phenomena such as the squeal. To avoid performing a full model updating which is often time consuming, the use of the ...
