... Structure dynamics Vibrations In Figure 3 , it can be seen that the deformation characteristic occurring at this eigenfrequency is mainly dominated by plate bendings of the housing, i.e. the cooling jacket and the plates connecting the feet of the induction machine. These bendings are much more...
