Vibrodiagnostic device is intended for:

• detection of fatique cracks in stringers, frames, thermocompensators being closed by vehicle skin, brackets, control rods, tank shells and jet engine bodies, in bodies of buses, cars, waggons and other thin-walled constructions
  
• detection of defects in thin multilayer constructions of composite materials, for example delimination, disbond etc.
  
• detection of destroyed rivets, internal corrosion of pipes and other closed objects
  
• determination of turbogenerator and electric motor winding state
  
• determination of hardness reduction due to stress relaxation in abutment joints of metal constructions or reduction of elasticity moduls in glass-reinforced plastics, rubber articles and belts

The principal distinction of proposed local vibromethod is determination of oscillation frequency not of the object, but free oscillation frequency of jointed vibroexciter at the piont of its application. This releases from labour-consuming process of calibration against a basic object and roughly increases the method's sensitivity in comparison with integral method.

Thanks to simplicity of the construction the expenditures for technical maintenance repairing and service are negligible.
