Evaluation of Axial Preload in Different-Frequency Smart Bolts by Laser Ultrasound
We report here on a laser ultrasonic system to indirectly evaluate the preload force of different-frequency piezoelectric bolts. This newly developed system enables us to achieve the goal of non-contact excitation and synchronously collects the laser-induced ultrasonic signal by the combination of a...
