A methodology for simultaneously balancing of several modes of vibration for a rotor bearing system by mean the so-called active balancing disk is presented in this paper. In order to determine the magnitude of the unbalance and its angular position on the rotor. it is proposed an on-line identifier based on algebraic identification. A mathematical model was developed for a multiple d... https://lightspeedlovers.shop/product-category/clit-and-nipple-clamps/
