Design of Roll-Screen System Using Ultrasonic Motor

Journal of the Korean Institute of Illuminating and Electrical Installation Engineers, 2005
For silent operation, Roll-Screen has been designed by using piezolelectric ultrasonic motor. To drive the ultrasonic motor, a digitally controlled drive system has been designed by using PLD. And to measure the position and velocity of Roll-Screen, encoder with 36 pulse/revolution is used.

Study on Ultrasonic Surface Rolling Process Using FEM Analysis

Advanced Materials Research, 2011
Ultrasonic surface rolling processing (USRP) is a surface nanocrystallization method developed recently, which can bring metal surface with superior properties. In order to obtain the material response during USRP, a 3D dynamic finite element model was adopted to study the effects of parameters.

Effect of Ultrasonic Deep Rolling on High-Frequency and Ultrasonic Fatigue Behavior of TC4

2019
A gradient nanostructured (GNS) surface layer was produced on TC4 samples by means of ultrasonic deep rolling (UDR). Grain size refined to nano-scale and increased to macro-scale with the increasing depth. The microstructure of the UDRed sample was observed and the mechanical properties of UDRed samples were measured.

Optimized Design of the Horn of Ultrasonic Roll Welding

Advanced Materials Research, 2012
Previous studies on the amplitude horn only calculated sizes in consistent with the axial resonant mode frequency and disc bending resonant mode frequency without considering the overall stress and the amplitude of the disc’s outer ring. The resonant frequency of the amplitude horn cannot occur around 35 kHz.

Ultrasonic monitoring of texture in cold-rolled steel sheets

The Journal of the Acoustical Society of America, 1988
An ultrasonic method is tested for the nondestructive evaluation of rolling recrystallization texture in cold-rolled steel sheets. To determine three orientation distribution coefficients (ODCs) of the fourth order, propagation velocities were measured of the longitudinal and shear waves in the thickness direction and the shear-horizontal (SH0) plate ...
