Dynamic tests

The behavior of structural elements is determined not only in static tests, but also as a result of dynamic tests. This type of strength tests, which are one of the basic methods of evaluating the properties of structures and their elements, enable the determination of dynamic mechanical properties. Dynamic tests play an important role in the case of objects intended for operation under dynamic load conditions.

Dynamic tests – testing capabilities

We perform dynamic strength tests of complete structures and their elements. We perform structural tests according to individual Customer orders, including the preparation of the project and the construction of a test stand.

Dynamic tests – equipment:


The hammer is intended for testing shock absorption of aircraft landing gears in conditions similar to those of landing and taxiing, testing “shimmy” vibrations of landing gears, as well as testing brakes, wheels and tires. The stand allows to apply dynamic loads in the form of driving over an obstacle.

Test stand specification:

  • maximum weight of the object with mounting elements: 3 T (expandable to 6.5 T for wheel tests);
  • maximum vertical force when dropping: 118 kN;
  • maximum rotational speed of the treadmill: 800 rpm;
  • maximum perimeter speed of the treadmill: 58.6 m/s;
  • treadmill diameter/width: 1400 mm/530 mm;
  • moments of inertia of the treadmill (adjustable):
    • I1 = 294 kgm²,
    • I2 = 550 kgm²,
    • I3 = 588 kgm²,
    • I4 = 843 kgm².

Testing characteristics:

  • dynamic tests (drops),
  • shimmy tests,
  • approaching an obstacle,
  • brake tests,
  • wheels rolling.


The 10 T hammer is designed to test landing gear shock absorption in conditions similar to those of landing. It is also possible to perform  impact tests, for example, on dampers or shock absorbers, as well as tests to determine the energy absorption capacity (crash).

Test stand specification:

  • maximum weight of the object with mounting elements: 10 T;
  • maximum forces when dropping:
    • vertical force 392 kN,
    • horizontal force 196 kN,
    • lateral force 157 kN;
  • maximum rebound pressure (unloading): 3 MPa;
  • maximum acceleration speed of the wheel: 111 m/s;
  • maximum speed of descent: up to 8 m/s – depending on the height of the tested object.

Testing characteristics:

  • dynamic tests (drops),
  • static tests of the wheels,
  • functional tests.
