FIELD: measuring instrumentation.SUBSTANCE: invention refers to measuring instrumentation, particularly to mechanical vibration parameter measurement in a wide frequency range. Invention can be applied for measurement of mechanical vibration wave parameters in various objects in construction, mechanical engineering, acoustics, etc. Proposed method of mechanical vibration detection and transformation is implemented with 3D detector in the form of triangular pyramid with sides equi-inclined against the pyramid base at a given ? angles, while removable detection units (vibration blocks) are positioned in the centre of each side in a definite point of symmetry axis, allowing for spatial, physical and electrical superposition of information on vector components in the measurement point and for reliable measurement of mechanical vibration vector.EFFECT: method and 3D detector for highly reliable detection and simultaneous tensor transformation of components of measured mechanical vibrations in the whole range of diagnostic parameters of an object.2 cl, 2 dwg |
