Abstract: Wayside acoustic defective bearing detector (ADBD) system is a potential technique in ensuring the safety of traveling vehicles. However, Doppler distortion and multiple moving sources aliasing in the acquired acoustic ...

Abstract: Momentum wheel assemblies (MWAs) play an important role in the attitude adjustment of the satellite by momentum exchange. The micro-vibration induced by the MWAs affects attitude adjustment and leads to unclear imaging and ...

Abstract: In this work, the three-dimensional fluid–solid interaction vibration of particle in the oscillating resonator and its effect on the dynamic characteristics are analyzed and discussed. It demonstrates that the displacement ...
