Dynamic Testing

Services

  • Tests of strength and fatigue life of structures and their parts at the simulation of real operational loading by means of electrohydraulic loading systems (including the simulation of response to oparational loading)
  • Fatigue tests of structural materials at temperatures up to 600 °C
  • Seismic resistance and vibration resistance tests
  • Fall tests of products up to the mass of 15 t
  • Laboratory strain gauge measurements of uniaxial and plane stresses
  • Strain gauge measurements of structures and machines stresses under operational conditions (including measurements on rotating parts of machines, in magnetic field, in corrosive atmosphere, at temperature range from -269 °C to 500 °C )
  • Calculation prediction of the operational fatigue life
  • Measurement of technological and residual stresses

Technical equipment

  • IST Labtronic 8800 24-channel fully digital control system with RS TWR module for the precise reproduction of real measured signals during operation
  • Set of servo-cylinders of a loading power from 7 kN to 630 kN and operating stroke from 20 to 250 mm
  • Foundation structure of 11.5 x 14.5 m with the Schenck 4000 multi-purpose modular clamping and support system
  • Two cushioned clamping blocks, dimensions 4 x 4 and 4 x 8 m, clamping area 5 x 10 m
  • Two vibration tables - vertical table - 1200 mm x 1600 mm, maximum loading 3000 kg, maximum stroke 100 mm, maximum acceleration 6 g; horizontal table - 1400 mm x 2500 mm, maximum loading 3000 kg, maximum stroke 250 mm, maximum acceleration 8 g
