Modal Testing: Tsinghua University, Beijing, Uses SO Analyzer

The renowned Tsinghua University in Beijing successfully uses m+p international’s  SO Analyzer impact testing software to perform modal tests on helicopter rotor blades. These tests are done to study the coupled/uncoupled behavior of the blade which is exposed to wave, shimmy and torsional modes.

The acquired modal parameters (natural frequency, mass and damping) enable optimization of the blade design such that it cannot resonate with the air harmonic excitation. The test results can also be used as input for flutter evaluation.
