Main functions
The combined static/dynamic impactor enables impact tests to be carried out in any orientation (horizontal or vertical). The shocks are generated by a linear ram driven by an electric servomotor. By measuring position and velocity relative to the impacted object, we can measure the potential energy of the impact and the energy absorbed by the sample. The position and orientation of the impact are adjustable and motorized. The bench can also perform static compression tests up to 80 kN.
Operating mode
The machine is attached to a test stand or directly to the component to be tested. This is achieved using a system of automatically controlled tightening straps, eliminating the need for a large gantry (for testing on an aircraft, for example). The user sets the position and orientation of the impactor. The test bed automatically searches for a contact position. The impactor is then propelled at a controlled speed over the product/sample. The impactor is automatically caught up to avoid rebound shocks. The differential impactor/target position is measured by laser.
Combined static-dynamic impactor
The dynamic test bench enables impact tests to be carried out in any orientation (horizontal or vertical).
Hanging
Autonomous attachment to the product under test using self-tightening straps.
Airframes
Simulated impact between a runway vehicle and an aircraft on the tarmac.
Orientation
Shooting possible in all directions with motorised adjustments.
Impactor Static Dynamic combined
Impact tests on the fuselage of a “test” aircraft. The tests carried out are used to reproduce deformations, in order to estimate the force, energy and impact velocity criteria that generate this type of defect.
Advantages of the Combined Dynamic Static Impactor
Wind turbine mats
Simulation of impacts on a wind turbine mast.
Large-diameter tubes
Behavior of a tube subjected to a static point load.
Positioning
Precise shot positioning thanks to automatic X/Z adjustment with laser sight.
Diameter adjustment
Adjustable pad position to suit product diameter.
