“…The test data show that the damping performance of the damper is better than that of the conventional damper, and it can still work normally under the low frequency vibration ≤ 30 Hz 12 . The simple ball impact damper was applied to improve vibration suppression, and the calculation results of numerical model adopted was consistent with the test results 13 . A damper with soft and hard mixing particles was presented.…”

A particle damper is applied to suppress the longitudinal vibration of underwater vehicle shafting in order to reduce vibration level and improve silence and stealth of underwater vehicles. The model of rubber-coated steel particle damper was established with discrete element method and PFC3D simulation software, the damping energy consumption law of collision and friction between particle and damper and between particle and particle investigated, the effects of particle radius, mass filling ratio, cavity length, excitation frequency, excitation amplitude, rotating speed and both stacking and motion states of particles on the system vibration suppression were discussed, and the bench test was carried out to verify the law. It revealed the mechanism of longitudinal vibration suppression of particle damping, established the intrinsic relationship between of total energy consumption of particle and vibration of system, and put forward the evaluating method of longitudinal vibration suppression effect by total energy consumption of particle and vibration reduction ratio. The research results show that the mechanical model of particle damper is reasonable and the simulation data is reliable; the rotating speed, mass filling ratio and cavity length have significant effects on the total energy consumption of particle and vibration reduction ratio.

The simple ball impact damper was applied to improve vibration suppression, and the calculation results of numerical model adopted was consistent with the test results 13 . The calculation results of 3d DEM was veri ed by test data, and found that the additional damping of the test device was actually the sum of both impact and friction damping, which resulted in linear attenuation of the amplitude of the primary system 14 .…”

“…Tuned mass damper (TMD) is a passive device comprising of a mass attached to the main structure using a T A B L E 1 Overview of the literature in the field of SC, SHM, energy harvesting, integrated systems, and related methodologies Wang, Zhou, & Lu, 2018). Particle impact dampers consist of a single particle or multiple particles located inside a container that can dissipate energy due to the particles' impacts or the impact between the particles and the container sidewalls (Djemal et al, 2019;Lu, Wang, Masri, & Lu, 2018). Multi-level pipe dampers (Cheraghi & Zahrai, 2016) combine multiple control devices that have been used to reduce the vibration of 5-, 10-, and 15-story 3D steel buildings subjected to earthquake loading (Zahrai & Cheraghi, 2017).…”

Cities that are adopting innovative and technology-driven solutions to improve the city's efficiency are considered smart cities. With the increased attention on smart cities with self-driving vehicles, drones, and robots, designing smart infrastructure is only a natural extension. Smart infrastructures aim to self-diagnose, self-power, selfadapt, and self-heal during normal and extreme operating conditions. Structural vibration control (SVC) and structural health monitoring (SHM) technologies, in particular, are expected to play pivotal roles in the development of modern smart and resilient structures. SVC methodologies intend to provide supplemental damping and reduce the structural dynamic responses during normal and extreme events. SHM methodologies offer valuable information about the structure's condition that is useful for maintenance purposes and rapid damage detection in post-hazard events. The collapse of the 12-story Champlain Towers South, a beachfront condominium in the Miami suburb of Surfside, Florida, could have been known in advance with an embedded SHM technology. More recently, the integrated structural control and health monitoring (ISCHM) systems have shown promise in the development of smart cities of the future. The integrated architecture incorporates the control and health monitoring components as complementary technologies and simultaneously takes advantage of both technologies. This article provides a state-of-the-art review of ISCHM ideas and systems. It presents recent significant developments in structural control, SHM, and energy harvesting that are paving the way towards the advent of integrated ISCHM systems, including damage-tolerant control systems. This article also identifies future promising research areas for designing the next generation of autonomous ISCHM systems for smart cities.
