Phononic crystals are composite materials consisting of periodically distributed inclusions, and this structure enables wave band gaps under specific conditions. This characteristic allows for the suppression of elastic waves within certain frequency ranges, offering a new approach to vibration reduction and noise control. In this study, phononic crystals, with their periodic structure, tunable bandgap properties, topology optimization, and additive manufacturing technology, are reviewed. Some key hot issues, such as low-frequency vibration and noise control, intelligent materials, and tunable bandgap design, are discussed. In the future, phononic crystals will play a significant role in barrier vibration isolation, rail transit vibration isolation, power equipment vibration isolation, precision equipment vibration isolation, noise control, and underground protection engineering. This study constitutes a systematic summary and outlook of phononic crystals in modern engineering vibration and noise control. © The Author(s) 2025.

Noise and vibration Worldwide 2024年第11期55卷 632-650页

In recent years, magnetorheological dampers (MRD) have played a significant role in vibration control in various fields such as vehicles, military, building structures, etc. However, the mechanical model of MRD is very complex due to its hysteresis, which makes it difficult to identify the model’s parameters. In addition to experimental data, under the condition of no other prior knowledge, eight unknown parameters of the Bouc-Wen model are identified in this study based on the particle swarm optimization (PSO) algorithm. According to the trend of parameter variation with current, fitting research is conducted, and the variation law of parameters with current is summarized. Based on the identified parameters, the MRD’s output force is predicted under any current other than the experimental current. Subsequently, the application of MRD in semi-active control of power equipment is performed out, and proposed Simulink calculation programs for single-stage and two-stage vibration control systems are built. Then, a comparative study with passive and active control is conducted. In this paper, linear quadratic regulator (LQR) control is adopted for the active control, and the controller’s parameters are optimized based on the PSO algorithm. The results show that the adopted semi-active control can significantly reduce the transmitted force from power equipment to the foundation and can effectively mitigate the disturbance of power equipment to the environment. This study offers important guidance for the vibration control of MRD in industrial engineering. © The Author(s) 2024.

To provide a highly applicable tool, which can assess the damage level and traffic capacity of girder bridges accurately and quickly, we proposed a new rapid assessment model for girder bridges, which contains a vulnerability model with parameter modification and a fast evaluation method for traffic capacity. Based on this model, we developed a rapid assessment software for girder bridges, using Visual C++ and ArcGIS Engine, in which the damage level and traffic capacity of girder bridges post-quake can be highlighted with colourful segments in the road network. Furthermore, we illustrated the functions and usages of this software through an application example. © Published under licence by IOP Publishing Ltd.

To establish the optimal design method of multiple tuned mass damper（MTMD）for the footbridge considering the vertical human-structure interaction，the parameters randomness of the mass-spring-damper（MSD）pedestrian model is simulated，and the vertical dynamic response of the random crowd-footbridge-MTMD system is calculated based on the pseudo-excitation method. Then，the effect of vertical human-structure interaction on the dynamic response of the footbridge-TMD system is demonstrated. Finally，based on the H2 performance of the acceleration transfer function and response surface methodology of the coupled system，an optimal design method of MTMD for footbridge vibration control considering vertical human-structure interaction is established. The results show that the dynamic response calculation method of the coupled system avoids a large number of nonlinear time history analyses，and the power spectrum and root mean square of the coupled system response can be obtained efficiently. The vertical human-structure interaction makes the TMD detuning effect significant，and the reduction rate of TMD with 3% mass ratio decreases by 37.19% when the crowd density increases from 0.25 person/m2 to 1.25 person/m2. The proposed MTMD optimization design method for footbridge has an average mitigation rate of over 70% for footbridge acceleration response. © 2025 Nanjing University of Aeronautics an Astronautics.

Remote online experimental system is the inevitable trend of experimental teaching in the future. Compared with the traditional offline experimental mode, the online experimental system has better operability and more intuitive teaching significance. It can carry out experiments anytime and anywhere without many actual environmental restrictions, saving the time of teachers and students. The number of students in an online class is far more than the number of offline experiments, which can improve teachers' teaching efficiency and teaching quality. This paper will start from an experimental example, design the simulation system based on Automation Studio (AS) and build the actual system based on WS290 hydraulic experimental rig, and then design the image recognition remote control program, and let users achieve the purpose of experimental teaching and control through the program. © 2023 ACM.

This study introduces a new design for an acoustic membrane structure that utilizes a parallel-arrangement of mixed foil sound resonators to enhance sound absorption and insulation capabilities in the low to medium frequency range. The structure consists of a single layer with a combination of parallel-arranged mixed foil square wedge-shaped coffers and bottom flat panel separated by an air cavity. The incident sound waves treat the mixed thickness-based foil resonators as a combination of independent resonators with unique resonance frequency, improving the sound insulation with broadband effectiveness. A parametric study was conducted using FEM based COMSOL Multiphysics, and the expected results were obtained. The study found that the broadband sound transmission loss (STL) can be adjusted by modifying both top and side wall thickness, bottom plate thickness, and depth of back cavity. The results indicate that the current acoustic membrane structure can be very effective, with an average STL of more than 40 dB ~ 45 dB within the low to medium frequency bandwidth of 500 Hz ~ 3200 Hz. Experimental validation was performed inside an anechoic chamber room, and the results are fairly aligned with FEM simulation results. Compared to conventional uniform foil sound resonator based acoustic membranes, this mixed single-layer square wedge-shaped foil resonator based acoustic membrane provides exceptional sound insulation performance within low to medium frequency range due to its lightweight structure and conventional manufacturing availability. This enhanced form of the foil sound resonator based acoustic membrane has great potential in acoustics and noise control applications in domestic, commercial and industrial environments. © 2023, The Authors.

In this paper, we propose a positioning algorithm based on sonar images, which is mainly used for the positioning of underwater robots, so that the robots can obtain the position information in real time when operating underwater and avoid colliding with the underwater walls. First, the underwater space was detected with multibeam sonar, and the sonar images of the underwater space wall were found to have line segment characteristics;Composite denoising, threshold segmentation and Canny edge detection are applied to the sonar image to extract the contours of the underwater spatial wall. Then the characteristic line segments of the underwater spatial wall are detected based on the LSD (Line Segment Detector) line segment detection algorithm. In terms of line segment classification, a method is proposed to effectively classify line segments using the origin of the sonar image and the slope of the detected line segment. To further demonstrate the effectiveness of the localization algorithm in this paper, the specific steps of the algorithm are illustrated with the example of underwater rectangular space. © 2022 IEEE.
