Abstract: This study investigates the dispersive properties of ridge waves that travel circumferentially around piezoelectric circular ridge waveguides and investigates their resonant modes. Based on the variable separation method ...

Abstract: This study applied appropriate assumptions to simplify a surface acoustic wave (SAW) motor model, as well as the elastic friction layer concept to analyze the two-dimensional contact problem. The effect of inertial force ...

Abstract: This study investigated the dynamic displacement response of an elastic friction layer under load by simplifying a circular cylindrical wedge-wave ultrasonic motor (WW-USM) to a two-dimensional (2D) contact problem through ...
