COMBINED VIBRATION AND STRAIN GAUGE ANALYSIS FOR DIAGNOSTICS OF INDUSTRIAL MACHINES

Vibration Diagnostics for Industrial Electric Motor Drives

Vibration Diagnostics of Electrical Machines by means of Optoelectronic Sensors

Abstract: The proposed method allows determining the level of wear of the bearings of electric machines by means of rotor radial displacement during operation. Measurement is effected by non-contact method and optoelectronic sensor which converts the rotor mechanical motion into electric signal. Received informational signal is recorded and processed by computer system. Based on the processed i...

Strain gradient torsional vibration analysis of micro/nano rods

Fabrication, characterization and application of micro-/nano-rods/wires are among the hottest topics in materials science and applied physics. Micro-/nano-rod-based structures and devices are developed for a wide-ranging use in various fields of micro-/nanoscience (e.g. biology, electronics, medicine, optics, optoelectronics, photonics and sensors). It is well known that the structure and prope...
