摘要：

The use of a tunable vibration neutralizer for the control of global vibration of a structure is discussed. With local vibration control, where the aim is for the vibration neutralizer to pin the structure at the point of attachment, the dynamic stiffness of the neutralizer is required to be as large as possible. A tuned vibration neutralizer can result in an increase other than decrease in global vibration. By correctly positioning the neutralizer natural frequencies can be tuned to be a resonant device and effect global control of the structure, that offers a performance within 3 dB of that achievable with optimal passive control.
