“…Both in the PTMD studies of Song [36] and Wang [37], VE materials were used as energy dissipating material. The performance in previous experiments proves that VE materials are suitable as an energy dissipating material for PTMD [45,66,67].…”

“…In the previous study by the authors [45], the TMD and VE-PTMDs were tested for the vibration control of the same piping system. For comparison, in this experiment, the mass and the swing arms of PTMD are identical to the previous study [45], except that the VE material is replaced by an SMA sponge. Figure 4 shows these two different energy dissipating materials.…”

“…In this paper, the SMA is chosen as energy dissipating material for single-sided PTMD to improve its vibration control performance. To better understand the effectiveness of SMAs in energy dissipation, the vibration control effects of single-sided SMA-PTMDs are studied, and the results are compared with TMD and VE-PTMDs tested in a previous study conducted by the authors [45]. The PTMDs are employed to suppress the same suspended piping system under the same excitation conditions.…”

“…In recent years, PTMD has been extensively studied for implementation in different types of facilities [37][38][39][40], including frame structures [41], subsea jumpers [42,43], power transmission towers [44], etc. In a previous study by the authors [45], two types of PTMDs (spring steel type and pendulum type) associated with viscoelastic (VE) material were designed. The results indicated that VE-PTMDs performed well in suppressing the vibration of a suspended piping system.…”

“…In this paper, two types of PTMDs are employed to suppress the vibration of suspended piping systems. Unlike the previous experiments [45], the energy dissipating material is changed from VE material to shape memory alloy (SMA). The SMA-PTMDs are tested in free vibration and forced vibration, and the control performances are compared with a TMD control and a VE-PTMD control.…”

Piping systems are important nonstructural components of most types of buildings. Damage to piping systems can lead to significant economic losses, casualties, and interruption of function. A survey of earthquake disaster sites shows that suspended piping systems are flexible and thus prone to large deformation, which can lead to serious damage of the piping systems. The single-sided pounding tuned mass damper (PTMD), which is an emerging vibration suppression tool, has the potential to serve as a cost effective and non-invasive solution for the mitigation of vibration in suspended piping systems. The operating frequency of the single-sided PTMD can be tuned similarly to a tuned mass damper (TMD). The single-side PTMD also possesses high energy dissipation characteristics and has demonstrated outstanding performance in vibration control. One of the key factors affecting the performance of the PTMD is the damping material, and there is a constant search for the ideal type of material that can increase the performance of the PTMD. This paper explores the use of shape memory alloy (SMA) sponge as the damping material for two types (spring steel and pendulum types) of PTMDs to mitigate the vibration of a suspended piping system. The PTMDs are tested both in free vibration and in forced vibration. The results are compared with no control, with a TMD control, and with a viscoelastic (VE) material PTMD control. The results show that in free vibration tests, SMA–PTMDs attenuate the displacement of the piping system significantly. The time to mitigate vibration (i.e., reduce 90% of the vibration amplitude) is reduced to 6% (for spring steel type) and 11% (for pendulum type) of the time taken to mitigate vibration without control. In forced vibration tests, the overall magnitudes of the frequency response are also lowered to 38% (spring steel) and 44% (pendulum) compared to vibration without control. The results indicate that SMA has the potential to be a promising energy dissipating material for PTMDs.

Fluid-conveying pipes are widely used to transfer bulk fluids from one point to another in many engineering applications. They are subject to various excitations from the conveying fluids, the supporting structures, and the working environment, and thus are prone to vibrations such as flow-induced vibrations and acoustic-induced vibrations. Vibrations can generate variable dynamic stress and large deformation on fluid-conveying pipes, leading to vibration-induced fatigue and damage on the pipes, or even leading to failure of the entire piping system and catastrophic accidents. Therefore, the vibration control of fluid-conveying pipes is essential to ensure the integrity and safety of pipeline systems, and has attracted considerable attention from both researchers and engineers. The present paper aims to provide an extensive review of the state-of-the-art research on the vibration control of fluid-conveying pipes. The vibration analysis of fluid-conveying pipes is briefly discussed to show some key issues involved in the vibration analysis. Then, the research progress on the vibration control of fluid-conveying pipes is reviewed from four aspects in terms of passive control, active vibration control, semi-active vibration control, and structural optimization design for vibration reduction. Furthermore, the main results of existing research on the vibration control of fluid-conveying pipes are summarized, and future promising research directions are recommended to address the current research gaps. This paper contributes to the understanding of vibration control of fluid-conveying pipes, and will help the research work on the vibration control of fluid-conveying pipes attract more attention.
