Vibration Testing

Vibration testing is used to simulate the launch ambiances to the unit under test. This ensures that the rocket’s payload can survive the launch and reach orbit without its functioning being impaired. IRF Kiruna operates in close collaboration with the Swedish Space Corporation (SSC) and Luleå University of Technology (LTU) in this field.

The shaker used at IRF is a Sentek Dynamics M4040A-PA140 System.
