Background The electro-hydraulic shake table (EHST) is an essential equipment for vibration tests. When performing sinusoidal vibration excitation, the acceleration response suffers from amplitude attenuation, phase delay, and harmonic distortion, which reduces the accuracy of the vibration test. Purpose The filtered-x least …
