"Many industrial applications include model parameters for which precise values are hardly available. To better characterize these parameters, deterministic values are replaced by stochastic variables. These can be regarded as parameter uncertainties and potentially have a significant influence on the simulation results. The quantification of such uncertainties plays a crucial role, e.g., for unknown component tolerances or measurement errors. One of the challenges is to gain knowledge about the parameter distribution from experimental data. In this context, Bayesian inference offers an approach to combine numerical simulations with experimental data to obtain a better knowledge of the uncertainties. Many standard methods require a large amount of evaluations to achieve high numerical accuracy. This is a significant drawback, especially when the cost of a single forward simulation is very high. Meta models, such as Polynomial Chaos (PC) extensions, can significantly reduce the number of required evaluations. To validate the described methods and algorithms, in reality, a test bench was developed in the present work, with which a motor characteristic of an electric machine with uncertain physical parameters can be measured. With this test bench, it is possible to define physical reference parameters and to record a corresponding set of measurements. The focus is on the validation of the methods based on real measurements from an industrial application. The numerical results show that the PC approach can significantly reduce the required computing time compared to the original simulation model and thus make the method applicable in practice."^^ .
