Optimal design of V-type ultrasonic motor

Abstract：V-type ultrasonic linear motor fabricated using a simple punching technique was proposed to utilize as an actuator of small precision machine. The stator of the motor is composed of a thin elastic body and four ceramics attached to the upper and bottom areas of the body. The ceramics have each direction of polarization. When two harmonic voltages with a 90° phase difference are applied to the ceramics, symmetric and anti-symmetric displacements will generate at the tip to produce an elliptical motion. A finite element analysis (ATILA) was conducted to simulate the motion pattern for the contact tip of the stator. To develop a model that generates the maximum displacement at contact tip, the FEM program was used for various lengths. In addition, an optimal model was chosen by considering the magnitude and shape of the displacement according to changes in frequency. The maximum elliptical displacement is shown by W2L11 model, which has a ratio of ceramic width to length of 1:5.5. However, the displacement of the contact tip is reduced by the bucking phenomenon if the ratio is larger than 1:6. 作者： Author： JEONG S S  PARK C H  PARK T G 作者單位： School of Mechatronics, Changwon National University, Changwon 641-773, Korea 期 刊： 中南大學(xué)學(xué)報(bào)(英文版)   EISCI Journal： JOURNAL OF CENTRAL SOUTH UNIVERSITY OF TECHNOLOGY(ENGLISH EDITION) 年，卷(期)： 2010, 17(6) 分類號(hào)： U4 Keywords： ultrasonic motor    piezo-actuator    finite element method    optimal design    elliptical motion    機(jī)標(biāo)分類號(hào)： TM3 R4 機(jī)標(biāo)關(guān)鍵詞： ultrasonic motor    ultrasonic linear motor    finite element analysis    maximum displacement    optimal model    tip    difference    direction    addition    However    develop    changes    simple    upper    small    thin    four    two    FEM 基金項(xiàng)目： the Second Stage of Brain Korea 21 Project，the National Research Foundation of Korea
