FIELD: physics. ^ SUBSTANCE: dynamic model of a construction is delivered. According to it, the number N1 of parallel connected elements and number N2 of serial connected elements are defined. Number of test variants is assumed equal to the sum of parallel and serial elements N1+N2. Resonance oscillation is excited in standard construction variants with parallel elements disconnected. Resonance oscillation is excited in construction with serial elements jammed and parallel elements disconnected. On the basis of the dynamic model the number N2-1 of jammed serial elements is defined, in the first N1 variants any of N2-1 serial elements is jammed and each of N1 parallel elements is disconnected in turn. In an (N1+2)th variant the serial element jammed previously in the first N1 variants is jammed again, the other N2-2 serial elements are connected in the standard pattern, and all parallel elements are disconnected. In the next variants starting from (N1+3)th to the last but one, (N1+N2-1)th, each time any of the elements left connected is added to the elements jammed in the previous variants, so that in the last but one variant only (N2-1)th serial element is left connected, and all parallel elements are disconnected. Rigidity and damping properties of separate elements are calculated by the formulae. ^ EFFECT: extended applicability of the method without change to the precision of definition. ^ 5 dwg |
