FIELD: electricity. ^ SUBSTANCE: according to the invention, the method for performing indexing of a base and a piezodevice relative each other (the piezodevice containing a piezoelement with supports at its ends), based on generation of forces pressing the supports to the base and supplying voltage to the piezoelement, involves generation of non-identical friction forces between opposed supports and the base. For pressing the supports to the base pressing forces are used, unvarying during the indexing process. The voltage supplied to the piezoelement is asymmetric. Non-identity of the friction forces between opposed supports and the base is ensured by using materials with varied friction properties for the contacting surfaces and/or by pressing opposed supports with pressing forces varying in magnitude. The weight of elements of the structure resting on the supports and/or the weight of the supports proper is used as the pressing forces. ^ EFFECT: simplified design, reduced dimensions, enhanced operating frequencies and reduced noise level. ^ 15 cl, 10 dwg |
