Active vibration control of a fluid/plate system using a pole placement controller
TL;DR: In this paper, an experimental device mimicking an aircraft wing made of an aluminum rectangular plate equipped with piezoelectric patches at the clamped end and with a cylindrical tip-tank, more or less filled with liquid, was used for active reduction of the structural vibrations induced by sloshing of large masses of fuel inside a partly full tank.
Journal ArticleDOI
Ultrasonic Transducer for the Hydrothermal Method
TL;DR: In this article, the boundary conditions of the hydrothermal method were developed to apply ultrasound directly to the process transducer prototypes and the results showed that the sound field depends on the filling level and position and design of the transducers.
Journal ArticleDOI
Development of a dynamic pressure generator based on a loudspeaker with improved frequency characteristics
TL;DR: In this article, a measurement system with a dynamic pressure generator that is designed for the purpose of investigating the frequency characteristics of pressure connecting tubes was developed and analyzed, and the DPG dimensions were optimized with the help of physical-mathematical modeling.
An End-User's Guide To Centrifugal Pump Rotordynamics
TL;DR: In this article, the authors discuss the typical types of pump rotordynamic problems and how they can be avoided in most cases by applying the right kinds of vibration analysis and evaluation criteria during the pump design and selection/application process.

TL;DR: In this paper, a bulk synthesis of [100]-oriented TaC nanowires is accomplished by carbothermal synthesis through a direct vapor solid mechanism, and thermal resonance test results show that the synthesized square TaC Nanowires with cross-sectional side-lengths of 65 to 497 nm have a size-independent Young's modulus of (510.6±12.6) GPa; very close to the corresponding values of their bulk counterparts, but differing considerably from previously published measurements.
