... that this semiactive electromagnetic vibration absorber has a frequency adjustment range from 21 Hz to 25 Hz, in which considerable vibration reduction from 5 dB to 10 dB can be achieved. electromagnetic semiactive vibration absorber electromagnetic spring variable stiffness simulation test bench...

... overshoots. The under/overshoot happens alternately creating the zigzag pattern. This is a common result for general purpose testing equipment when used for characterization of variable stiffness materials/systems. However, the actual value of the applied preload never over- or undershoots by more than 3...
