摘要：
Operational Deflection Shape analysis was performed on a large fan foundation using normal background turbulence as the only excitation. The practical extraction of usable data from extremely small signals has recently become feasible by the introduction of analyzers using 24-bit front-ends combined with advances in measurement sensors.
