As we have
shown before, the rub can be represented by means of a local bow, i.e. a
couple, due to the friction between the rotor and the case or something
else like a sealing. Since we are interested to know where the rub occurred along the rotor, we identified the rub in a particular position of our rotor, which corresponds to the element 42 in the model of the rotor. | ![]() |
