Active control method of sliding bearing vibration by making use of piezo actuators and apparatus for making the same

摘要

method of active control vibration kluznu00fdch bearings using piezoaktuu00e1toru016f whose function is described in the form of block diagram in figure. 1, can be carried out so that the actual position y.sub.1.n.a y.sub.2.n.hu0159u00eddele (2) is measured in two mutually perpendicular directions through the first and second sensors (3, 4) position, due to the lou017eiskovu00e9mu sphere, and then deducted from the first desired location y.sub.1, sp.n.a second desired position y.sub.2, sp.n., while the result of the first and second control deviation e.sub.1.n.a e.sub.2.n.who are the entry dvouparametrovu00e9ho polohovu00e9ho regulator (12) and a pair of band filter laditelnu00fdch second order (13 and 14), whose porous frequency fw is derived from the frequency fr speed shafts (2), which is measured by the sensor (19), and outputs dvouparametrovu00e9ho polohovu00e9ho (12) and the two band laditelnu00fdch filters (13 and 14) in sumu00e1torech numbered first and second action quantity u.sub.1.n.and u.sub.2.n.a introduced as a voltage to a pair of amplifiers (17 and 18) of voltage, which is the first and the second piezoaktuu00e1tor (5 and 6), operating in two mutually perpendicular directions on the movable case (1) kluznu00e9ho bearings inside which turns the h u0159u00eddel (2).
