A study on the influence of excitation parameters and sensor configuration on the performance of ultrasonic longitudinal and transverse wave bolt preload detection

Accurate measurement of bolt preload is crucial for the safe service life of engineering structures. Addressing issues such as the lack of theoretical basis for parameter selection, insufficient signal stability, and limited measurement accuracy in traditional longitudinal and transverse wave bolt preload testing, this...

A new method for detecting bolt preload based on a combination of longitudinal and transverse ultrasonic waves

Accurate measurement of bolt preload is critical for ensuring the performance and operational safety of mechanical structural connections. However, traditional modal-conversion-based longitudinal and transverse wave (T-wave) testing methods suffer from low T-wave excitation efficiency, insufficient signal stability, an...

Structural Parameter Effects on Flow Stability and Classification Performance in a Turbo Air Classifier

Understanding which structural parameters govern flow stability and particle separation is essential for turbo air classifier design. In this study, the Y160L-6 turbo air classifier was used to examine whether different categories of spatial structural parameters influence classification performance through the same fl...
