Dynamic Modal Evolution of High-Speed Train Car Bodies Under Complex Boundary and Load Conditions: A Field Test Study

Stochastic Subspace Identification (SSI) theory offers the distinct advantage of extracting modal parameters directly from operational ambient excitations without requiring artificial force, ensuring completely true boundary conditions and providing extensive field measurement data. In this study, w...
