Vibration isolation by a periodic beam with embedded acoustic black holes based on a hybrid dynamics method

Journal of low frequency noise, vibration and active control (2023)

Bowen Yao Yanni Zhang Qinbo Zhou Bin He Xiaoting Rui

The acoustic black hole (ABH) has been proved to reduce broadband vibration response in beams and plates. While the traditional analytical and semi-analytical methods can only deal with the response of simple ABH structures; for complex ABH structures, the numerical methods such as the finite element method (FEM) have to be resorted and these methods are too often time-consuming. In this work, the vibration isolation by a beam structure embedded with periodic embedded symmetric ABHs is investigated. The vibration transmission of a single embedded symmetric ABH beam unit is first studied by the Riccati transfer matrix method (RTMM). A comparative analysis of the convergence speed and the computation efficiency of the unit by the RTMM and the FEM demonstrates the computation time using the RTMM increases linearly with the number of segments while that using the FEM increases exponentially and quickly exceeds the former as the number of segments increases. The computation time is consistent with the computational complexity associated with their respective algorithms. A hybrid dynamics method (HDM) is then proposed to derive for the vibration transmission solution of the beam with single and multiple periodically embedded symmetric ABHs. A comparison of the responses with those calculated by the RTMM demonstrates that the proposed HDM provides an efficient tool for solving the vibration response of the finite beam with periodic embedded ABHs, leading to much improved computational efficiency with ensured numerical stability and accuracy. This advantage in computation efficiency becomes even more obvious for larger structures when the number of the ABH units increased considerably. The proposed hybrid dynamic approach provides a basis for solving the vibration transmission/isolation problems of more complex ABH structures.

Novel Structure for Uplink mmWave Massive MIMO-HBF-NOMA Systems

2022 IEEE Wireless Communications and Networking Conference (WCNC) (2023)

Bin He Hui Wang Hong Wang Rongfang Song Qixin Tai

Massive multiple-input multiple-output (MIMO), non-orthogonal multiple access (NOMA), and millimeter-wave (mmWave) are key technologies in the upcoming beyond fifth generation (B5G)/sixth generation (6G) era. As mmWave massive MIMO will likely use hybrid beamforming (HBF) to reduce radio frequency (RF) chains without an obvious performance loss to fulfill the urgent requirement for immense connectivity and huge throughput, it is necessary to integrate mmWave massive MIMO-NOMA with HBF structure. This work devises a novel structure for uplink mmWave massive MIMO-HBF-NOMA system based on group-level successive interference cancellation (GSIC), aiming at maximizing the spectrum efficiency (SE) of the whole system. In our paradigm, users are grouped in terms of channel gain. Space division multiple access (SDMA) is deployed between users in the same group, while NOMA is applied among different groups. The analog beamforming vectors are selected through beam sweeping. An iterative algorithm is proposed to optimize the power allocation and the digital beamforming matrix. Therein, a quadratic transform (QT) algorithm is introduced to solve the power allocation and zero forcing (ZF) method is invoked to obtain the digital beamformer. According to the simulation, the novel GSIC-based structure outperforms the benchmark clustering-based successive interference cancellation (SIC) schemes in SE and energy efficiency (EE) measurably.

An Improved Matching Algorithm for the Underwater Navigation

2022 8th International Conference on Control, Decision and Information Technologies (CoDIT) (2018)

Zhiqiang Wu Yu Wang Zhonghai Pei Peng Wang Bin He

Considering that the terrain-aided navigation (TAN) system based on iterated closest contour point (ICCP) algorithm diverges easily when the indicative track of inertial navigation system (INS) is large, Kalman filter is adopted in the traditional ICCP algorithm. The difference between matching result and INS output is used as the measurement of Kalman filter. In this way, the cumulative error of the INS can be corrected in time by filter feedback correction, and the indicative track used in ICCP is improved. The proper number of matching points is designated by comparing the simulation results of matching time and matching precision. Simulation experiments are carried out according to the ICCP algorithm and the mathematic model. And it is demonstrated that the integrated navigation system is effective in preventing the divergence of the indicative track for the underwater, long-term and high precision of the navigation system for autonomous underwater vehicles (AUV).

The Construction Scheme Analysis and its Application of the Southern Portal Section of Urban Mountain Large-span Road Tunnel Under Shallow-buried Bias and High Voltage Tower in Zhuhai

IOP Conference Series Earth and Environmental Science (2021)

Gang Xu Yanjun Zhou Yutian Wang X G Li Bin He

The Heibaimian Jiangjun Mountain road tunnel is located in Nanwan District, Zhuhai City. The topography and geological conditions are complicated with challenges of high-voltage tower protection, shadow-buried bias load, under-passing water-supply tunnel and large-span section tunnel. To tackle these extremely unfavourable site conditions, the original construction scheme includes: i) a gravity retaining wall to overcome shadow-buried bias load, ii) a both side drift method with static blasting, controlled blasting, and conventional blasting and a tunnel body using a composite lining with curved wall and invert to resist section deformation of tunnel and protect existing infrastructures. However, this scheme involving multiple blasting techniques has seriously affected the construction progress of the west-line tunnel, becoming the primary threat to construction progress. To solve this problem, an flexible and pragmatic engineering countermeasure with a controllable cost and without sacrificing safety is proposed, by adjusting location of a south construction adit between the east and west tunnels. Besides, improvements on tunnel face excavation method and relative blasting parameters, as well as the optimization of construction scheme at the southern portal section, are proposed to accelerate the construction progress of the west tunnel. The proposed countermeasure provides important technical support for tunnel construction and is successfully applied to this engineering practice.

Double threshold control genetic algorithm based on optimal protection

2019 International Conference on Image and Video Processing, and Artificial Intelligence (2019)

Bin He Yuxing Zhang Yu Wang Lihua Zhu Zhiqiang Wu

In view of the disappointing phenomenon that genetic algorithm is trapped into the local minimum in application of complex problems easily, the double thresholds are introduced to dynamically adjust the similarity of the parents and mutation probability. The proposed algorithm helps to enhance the crossover effectiveness and the population diversity, improving the search efficiency of the algorithm. Besides, the added optimal protection guarantees the optimal individual undestroyed while expanding the population searching area. After all, the improved genetic algorithm is tested by using 164-point TSP model. The experimental results show that the improved genetic algorithm find new resolution and improve the searching efficiency when the population evolution stagnates. And comparative simulations with parameter pairs could provide the theoretical instructions of selecting the thresholds and coefficients for scholars.
