FIELD: technology for measuring mechanical forces, effective in metallic structures of ferromagnetic materials.
SUBSTANCE: method includes measuring double amplitude of strength of magnetic field of dissipation at magnetized portion of metallic structure. Measuring is firstly performed in metallic structure in loaded state. Then load is removed and applied again. Mechanical forces are determined on basis of alternation of double amplitude of strength of magnetic dissipation field as a result of lifting and restoring dosed load, and a previously produced calibrating graph.
EFFECT: increased efficiency.
