Abstract

As a stay cable is prone to vibrations due to its low inherent damping, a common method to limit unwanted vibrations is to provide an external force by installing a viscous damper near one of the cable supports. This paper analyses the performance of linear passive absorbers, consist of damper(s), spring(s), and inerter(s). The inerter device is the true network dual of spring, which force is proportional to acceleration between its two terminals. The linear passive absorbers can either be simple predefined networks or presented by a general positive-real transfer function. A finite element stay cable is used for this study. This method is able to obtain damping performance for stay cables with any absorbers with positive-real mechanical impedance. The ability to improve model damping of the cable for a set of absorber structures has be presented in a systematic manner.
