Abstract

A method and 3D detector for measuring a vector of mechanical oscillations. The invention relates to the field of measurement technology and particularly to measurement of parameters of mechanical oscillations over a wide frequency band. The proposed method for detection and conversion of a vector of mechanical oscillations is realized using a 3D detector in the form of an equilateral trihedral pyramid with the faces isoclinic to the pyramid base at specified angles φ, and that detachable detection units (oscillation dipoles) are located in the center of each face at a specified point of its symmetry axis, which makes it possible to spatially, physically and electrically align information on the vector components and reliably measure the vector of mechanical oscillations. The invention can be used for measurement of wave parameters of mechanical oscillations of various objects in

Claims

1. A method for reliable determination of the vector of mechanical oscillations over a broad frequency band comprising the process of synchronous measurement of three components of the vector of mechanical oscillations using sensing elements located on faces of the housing of a 3D detector, with the faces forming a trihedral pyramid, wherein, in order to increase measurement reliability, the mechanical oscillation arrives synchronously from a detection point via an isotropic housing of the 3D detector at sensing elements located symmetrically on the detector housing and equidistant with respect to a measurement point of an object of monitoring, and in the sensing elements a tensor transformation of measured oscillations takes place, via same-type processes of “

tension-compression”

conversion in a direction of measurement axes intersecting at the measurement point, to signals that are proportional to the three components of the vector of mechanical oscillations, the components are resolved in a direction of the measurement axes that are spatially, physically and electrically aligned at the measurement point, which makes it possible to reliably measure magnitude and reconstruct in space the direction of the vector of mechanical oscillations.

2. A device in the form of a 3D detector of mechanical oscillations for measuring the vector of oscillations over a broad frequency band comprising three sensing elements attached to faces of an isotropic housing of the detector that are isoclinic to a housing base and form an equilateral trihedral pyramid with the base that is the base of the detector housing, wherein, in order to increase measurement reliability and improve production manufacturability, the sensing elements of the detector are made in the form of removable detection units, or oscillation dipoles, located circularly symmetrically and equidistantly with respect to a detector measurement point which aligns with the center of the detector housing base and is the common intersection point of a measurement axes of the oscillation dipoles, while mounting seats of the oscillation dipoles are located on an axis of symmetry of each face, and a measurement axes of the sensing elements form a pyramid that is mirror-symmetric with respect to faces of the detector pyramid, with a vertex at the detector measurement point.
