摘要
针对柔性结构主动振动控制系统, 求出了压电作动器在梁上的作用力, 利用ANSYS软件进行分析和仿真, 得到了在不同控制力作用下悬臂梁自由端的幅频曲线。结果表明, 通过合理配置压电传感器和作动器的位置、数目以及控制力的大小, 可以对梁的振动起到最佳控制效果。
For vibration control flexible structural active system, the force acts on the cantilever by piezoelectric actuator was calculated.Using ANSYS software,the amplitudefrequency curve of cantilever’s free end under different condition was obtained through simulation method.It is shown that the optimal control effect of the beam’s vibration can be obtained through appropriate selection of the position and number of the piezoelectric sensor/actuator as well as the control force.
