Ground vibration testing is a process of experimental evaluation of modal parameters of an aircraft / aerospace structure. The modal parameters are: natural frequencies, modal damping and mode shapes. The main objectives are;
To build the structural modal model of the aircraft
Generate input data for GVT based flutter estimation and flutter clearance
Verification of the distribution of stiffness and mass; further helps to update the mathematical model for obtaining the aeroelastic characteristics
Identify the change in dynamic behaviour of a design modified aircraft
Aircraft development programs
Aircraft upgradation and mod certification
Weapon integration
Dynamic similarity analysis
Certification of composite repair technology
LRU Installation certification
B&K modal shakers and amplifiers
Siemens SCADAS Lab hardware with 300+ channels
Siemens Test.lab Software with PolyMax based modal analysis tools
