Jan 1, 2008 · Stockbridge dampers are devices extensively used to reduce vibration amplitude on electric lines due to wind, avoiding the risk of fatigue on the line. Acceptable performance of dampers must be...

A Stockbridge damper is a tuned mass damper used to suppress wind-induced vibrations on slender structures such as overhead power lines, [1] long cantilevered signs [2] and cable-stayed bridges. The dumbbell -shaped device consists of two masses at the ends of a short length of cable or flexible rod, which is clamped at its middle to the main ...

Stockbridge dampers are devices extensively used to reduce vibration amplitude on electric lines due to wind, avoiding the risk of fatigue on the line. Acceptable performance of dampers must be maintained for a wide range of excitation frequencies, which have a correspondence with the wind velocity. In this paper a formal approach for ...

a Stockbridge damper. The main function of a Stockbridge damper is to absorb Aeolian vibration by creating destructive interference of resonance frequencies. Over the past years, there have been several research studies that focused on improving Stockbridge dampers [5].

Stockbridge dampers are devices extensively used to reduce vibration amplitude on electric lines due to wind, avoiding the risk of fatigue on the line. Acceptable performance of dampers must be maintained for a wide range of excitation frequencies, which have a …

A Stockbridge damper system can control the aeolian vibrations in a transmission line by dissipating excitation energy through the self-excitation of the damper system. Therefore, locating these resonant frequencies is a critical design consideration for a Stockbridge damper to determine the efficiency of spectral energy dissipation.

This research delves into the effectiveness of asymmetric Stockbridge dampers in mitigating wind-induced vibrations in power transmission lines, particularly focusing on an innovative damper design that generates more than four resonance frequencies.

Aug 23, 2024 · This paper focuses on two main research scopes regarding the design and adjustment of this damper: firstly, to understand the systemic behaviour of the developed Stockbridge damper and the bridge structure, and to study the sensitivity of the natural frequencies of the damper to the design parameters.

Dec 20, 2016 · The Stockbridge damper is used to control the aeolian vibration of a overhead transmission line due to the natural wind under a low velocity, between 1 m/s to 7 m/s.

PFISTERER vibration dampers can be equipped either with bolted clamp or with helical rod attachment. PFISTERER vibration dampers are installed world wide and are well proven in the most severe environmental conditions. PFISTERER vibration dampers are designed to: Control aeolian vibration in each span of the line within the internationally ...
