To investigate the response of gastric motility to whole-body vibration (WBV) exposure, electrogastrography (EGG) and gastric manometry were performed in 10 healthy male volunteers. Sinusoidal vertical vibration of three different frequencies (4 Hz, 8 Hz, and 16 Hz) with a constant vibration magnitude of 1.0 ms-2 (rms.) was randomly given to the subject seated on the platform of a vibrator for ...
Optimization of a Non-Traditional Vibration Absorber for Vibration Suppression and Energy Harvesting
This paper investigates the optimization of a non-traditional vibration absorber for simultaneous suppression and energy harvesting. Unlike traditional absorber, has its damper connected between mass base. An electromagnetic harvester is used as tunable damper. attached to primary system that subjected random base excitation. analytical study conducted by assuming excitation white noise. In ter...
Aiming at the negative vibration effect caused by increased unsprung mass of hub motor-air suspension (HM-AS) vehicle and unbalanced magnetic force (UMF) motor, a linear quadratic regulator (LQR) air control strategy based on genetic algorithm is proposed. Considering coupling road surface excitation UMF, model HM-AS established. Then, according to optimal theory algorithm, LQR controller desig...
