Two‐level global sensitivity analysis of the excitation contributions leading to acoustic noise in an electric motor for the purpose of robust optimisation
Résumé
This paper presents a sensitivity analysis methodology used for electric motor design. This innovative approach evaluates both global effects of parameter variations in their design range and of parameter deviations in their tolerance intervals on design objectives. For the purpose of robust optimization, this method helps to select the most influent design parameters and uncertain parameters, which are not necessarily the same. Suitable for any design approach, this method is particularly useful in dealing with objectives defined by non-linear and non-regular functions. In this paper, the method is applied to the sensitivity evaluation of an electric motor’s acoustic criteria. The objective functions are the levels of electromagnetic tangential excitations responsible for acoustic emissions. The output mean torque is another objective.
