Ground Vibration Testing (GVT) is a modal test technique specifically focused on aircraft and spacecraft. The natural frequencies, mode shapes and damping ratios obtained from GVT provide critical information for flight safety assessments including flutter and structural dynamics.
Ground vibration testing (GVT) measures the dynamic response characteristics of an airframe using multiple shakers and accelerometers with multiple input multiple output (MIMO) signal processing and analysis.
GVT also aids engineers in determining the modal characteristics for an entire airplane, and it is usually done late in the development phase.
Applications for GVT include new airframe designs and modifications to established designs of fixed wing aircraft, rotorcraft, and spacecraft.
