“…During particle collision with a controlled pipeline, the displacement-velocity trajectories of the controlled pipeline and particle form closed curves according to existing results (Masri and Caughey, 1966;He et al, 2021), as shown in Figure 4. The curve of the controlled pipeline is symmetric with respect to the plane origin, and that of the particle is approximately symmetric with respect to (d/2, 0).…”

“…In the current reports, only Jin et al (2021) designed a multi-particle damper to control vibration of aircraft pipelines, and its numerical simulation and test showed that it has a good damping effect. However, Masri (1969b), Nayeri et al (2007), and He et al (2021) have shown that the damping effect of a multi-particle damper is reduced when particles restrict each other's movement, which reduces momentum exchange efficiency between particles and the controlled structure. The type of particle dampers proposed by the above cannot be directly used for vibration control of pipeline structures.…”

Undesirable vibration in pipeline structures due to internal gas/liquid coupling, mechanical vibration, and water hammer action may cause machine shutdown, leakage, fatigue failure, and sometimes catastrophic explosion. It is necessary to design a device to mitigate pipeline vibration. This paper proposes a new type of particle damper, the multi-cavity particle damper (MPD). A mechanical MPD model is first proposed. Second, the analytical solutions of the MPD are given for the case of two symmetric impacts per cycle. A corresponding method for numerically simulating more general cases is also proposed, and the optimal movement distance is established using the analytical solution. Third, shaking table tests are carried out on pipeline structures controlled by an MPD subjected to harmonic excitation, and the control effects are verified. Finally, a parametric study is conducted, and the MPD design is discussed. The MPD is found to have a significant damping effect that can reduce the response by 98% in resonant cases. Shaking table tests verify the analytical solution, numerical simulation, and optimization method.

“…15 Designing the particle movement distance of MUSPD, the three-story steel frame test model is first equivalent to a singledegree-of-freedom structure using its first-order mode. Subsequently, the optimal particle movement distance is calculated using the MUSPD performance optimization method proposed by He et al 30 He's approach entailed a mechanical model for MUSPD based on a single-degree-of-freedom structure, addressing analytical solutions under harmonic excitation. It was established the relationship between the optimal particle movement distance and other pertinent parameters through analytical solutions.…”

“…The initial vibration conditions for the multi-particle dampers illustrated in Figure 1B are relative strict. Fortunately, a solution has been proposed by Wang et al 13 and He et al 30 in the form of a multiple unidirectional single-particle damper (MUSPD), demonstrated in Figure 1C. In this design, each particle possesses an independent container and is confined to move solely along the vibration direction of the structure due to sidewall constraints.…”

This study designed and manufactured a 1/5‐scale model of a three‐story steel frame structure. Various types of ground motions, including non‐long period (NLP) ground motions, near‐fault pulse type (NFPT) ground motions, and non‐pulse long‐period (NPLP) ground motions, were selected following the site conditions of the structure. The multiple unidirectional single‐particle damper (MUSPD) and its layout schemes were then designed. A series of shaking table tests for the three‐story steel frame with and without MUSPD were performed. Subsequently, a mechanical model of the multi‐degree‐of‐freedom structure with MUSPDs was established, and a corresponding numerical simulation method was proposed. The results revealed that MUSPDs achieved an average damping rate of 18.24% for peak and 27.41% for Root Mean Square (RMS). Notably, MUSPD exhibited a superior damping effect on the RMS of the structure compared to the peak. The distributing floor particle mass according to the first‐order mode of the structure resulted in excellent damping performance. Additionally, determining the particle movement distance for each floor involved calculating the optimal distance using a single‐degree‐of‐freedom structure. MUSPDs exhibited a better damping effect under NLP ground motions compared to NFPT and NPLP ground motions. The shaking table test results confirmed the rationality and feasibility of the proposed numerical simulation method, demonstrating a high level of accuracy.
