ON SIMULATION OF 3-AXIS SUSPENSION WIRE BLUE-RAY OPTICAL PICKUP ACTUATOR WITH INCLUDED ANGLE BETWEEN WIRES
摘要
Abstract
The model of 3-axia suspension wire actuator of blue-ray optical pickup is built. The actuator, with included angle between the wires, has three degrees of freedom of movement and the functions of focusing, tracking and tilt compensation. The spatial magnetic fields and the force conditions of the actuator are analysed by using finite element method ( FEM) as the means. Three modals of the actuator including tracking, focusing and tilting derived from modal analyses are of 50.470Hz, 54. 754Hz and 205. 23 Hz respectively, the errors are less than 1% compared with the experiment results respectively. Equivalent damping ratio system is employed to simulate the damping effect of damping rubber, and the characteristic curve-Doppler curve of the actuator is obtained through harmonic response analysis. Through the comparison with experiments, the model built is able to actually reflect the characteristics of the actuator.关键词
