Abstract ：
Aero-engines, pumps, and trains are widely used in transportation, maritime, aerospace, and other industries. However, these devices often operate in harsh and complex environments, making their internal components prone to failure. Thus, constructing a highly accurate fault diagnosis model is essential for ensuring the safe and reliable operation of machinery. However, most existing models require many labeled samples to build accurate training models, which is both expensive and difficult to achieve. Moreover, some models lack adaptability and often require adjustments to their structure or hyperparameters to suit new diagnostic tasks. To address these challenges, this paper proposes a few-shot fault diagnosis model based on multi-scale perception multi-level feature fusion image quadrant entropy (MPMFFIQE). The MPMFFIQE method uses the gramian angle summation field (GASF) to convert transient signals into images, preserving more detailed information about the mechanical state. The multi-scale perception multi-level feature strategy is then applied to sequentially enlarge and reconstruct feature maps at various levels, maximizing the extraction of fault-related information. Afterward, the fusion image quadrant entropy technique is proposed to combine nonlinear dynamic features from these feature maps, forming the mechanical MPMFFIQE feature set. Finally, this set is input into the harris hawks optimization support vector machine (HHOSVM) classifier to achieve fault identification. Results from three real-world case studies demonstrate that the proposed MPMFFIQE method improves accuracy by up to 12.90% in comparison with six feature extraction techniques. Furthermore, the proposed model achieves an accuracy rate exceeding 98.10% with just five training samples per state, representing up to a 27.48% improvement over six existing models. These findings confirm that the developed model can effectively and accurately diagnose mechanical faults in industrial applications using only a small number of training samples. Additionally, the model shows strong generalization across different mechanical equipment, highlighting its significant practical value. © 2024 Elsevier Ltd

Abstract ：
Due to the merits of high flexibility, great pulling force, and light weight, the pneumatic muscle (PM) is applied to realize the flexible driving control commonly. However, the inherent asymmetric hysteresis nonlinear characteristics affect its control accuracy seriously and tradition generalized Bouc-Wen (GBW) model and its variants cannot characterize the hysteresis of PM effectively. A novel improved generalized Bouc-Wen (IGBW) model is proposed based on the concave convex features of the PM hysteresis curve. The parameter identification effects of Levenberg-Marquardt algorithm (LM), gradient descent method, Newton iteration method, differential evolution algorithm (DE), particle swarm optimization algorithm (PSO), and genetic algorithm (GA) on the IGBW model are studied firstly. Then, the modeling capacity of IGBW model is checked by contrasting the modeling accuracy and identification efficiency of IGBW and modified symmetrical generalized Prandtl-Ishlinskii (MSGPI) models. Finally, the hysteresis compensation control strategy is designed based on the inverse model of IGBW, and its stability is analyzed. The experimental results manifest that the LM algorithm is much better than the other five estimation methods with regard to computational efficiency and identification accuracy. The IGBW model can illustrate the asymmetric hysteresis properties of PM with higher accuracy and efficiency, and the control behavior is ameliorated significantly after using the IGBW model.

Abstract ：
To enhance the generalization capability of rotating machinery fault diagnosis, a novel generalized fault diagnosis framework is proposed. Phase entropy is introduced as a new method for measuring mechanical signal complexity. Furthermore, it is extended to refined time-shift multi-scale phase entropy. The extended method effectively captures dynamic characteristic information across multiple scales, providing a comprehensive reflection of the equipment's state. Based on signal amplitude, multiple time-shift multi-scale decomposition subsignals are constructed, and a scatter diagram is generated for each sub-signal. Subsequently, the diagram is partitioned into several regions, and the distribution probability of each region is calculated, enabling the extraction of stable and easily distinguishable features through the refined operation. Next, the one-versus-onebased twin support vector machine classifier is employed to achieve high-accuracy fault identification. Case analyses of a wind turbine, an aero-engine, a train transmission system, and an aero-bearing demonstrate that the accuracy, precision, recall, and F1 score of the proposed framework are over 99.51 %, 99.52 %, 99.51 %, and 99.51 %, respectively, using only five training samples per state. The proposed framework achieves higher accuracy compared to nine existing models via deep learning or machine learning. The aforementioned analysis results validate the accuracy and generalizability of the proposed framework.

Abstract ：
Compared to fixed-bottom wind turbines, offshore floating wind turbines (OFWTs) are subject to more prominent forced vibrations that require control measures. Considering the limited space within the nacelle, this paper proposed a novel methodology for designing a tuned mass dampers (TMD) installed inside the tower. To achieve an optimal design, a 4-degree-of-freedom simplify dynamic model is established to predict the vibration characteristics of spar OFWTs quickly and accurately. A new TMD configuration installed inside the tower is proposed to reduce the effect of space limitation and to determine the stroke limitation Based on the proposed methodology, the stiffness and damping of the TMD are designed and optimized, and then the detailed structural parameters are calculated. The comparison results show that, the proposed TMD achieves a maximum peak suppression rate of 90.67% in tower top fore-aft deformation power spectral density, which is 19.92% higher than that of the TMD designed by the formula method. The proposed TMD can effectively address the problem caused by the space limitation within nacelle, and provide superior vibration suppression for spar OFWTs. © 2024 Elsevier Ltd

Abstract ：
To reduce the levelized cost of energy (LCOE) for offshore wind turbines, a novel wind–wave energy converter (WWEC) with a mass-adjustable buoy is designed. To analyze the impact of buoy mass variations on the system, a coupled comprehensive numerical model is established to simulate the aerodynamics of the turbine and the hydrodynamics of the platform and buoy. It is found that the occurrence of the buoy out of water significantly reduces the output power. Adjusting the buoy’s mass with suitable strategy can prevent the impact of slamming loads and improve the power output. The mass adjustment strategy is determined based on the output power of the wave energy converter under regular wave conditions. It is found that the mass adjustment strategy can significantly enhance the output power of combined system. The buoy does not move out of the water under the extreme conditions, which avoids the impact of slamming loads on system stability. Moreover, mass-adjustable buoys can reduce the risk of mooring line failure compare to a wind turbine without a buoy. © 2024 by the authors.

Abstract ：
To meet the high-precision positioning requirements for hybrid machining units, this article presents a geomet-ric error modeling and source error identification methodology for a serial-parallel hybrid kinematic machiningunit (HKMU) with five axis. A minimal kinematic error modeling of the serial-parallel HKMU is established withscrew-based method after elimination of redundant errors. A set of composite error indices is formulated to describethe terminal accuracy distribution characteristics in a quantitative manner. A modified projection method is pro-posed to determine the actual compensable and noncompensable source errors of the HKMU by identifying suchtransformable source errors. Based on this, the error compensation and comparison analysis are carried out on theexemplary HKMU to numerically verify the effectiveness of the proposed modified projection method. The geo-metric error evaluations reveal that the parallel module has a larger impacts on the terminal accuracy of the platformof the HKMU than the serial module. The error compensation results manifest that the modified projection methodcan find additional compensable source errors and significantly reduce the average and maximum values of geomet-ric errors of the HKMU. Hence, the proposed methodology can be applied to improve the accuracy of kinematiccalibration of the compensable source errors and can reduce the difficulty and workload of tolerance design fornoncompensable source errors of such serial-parallel hybrid mechanism.

Abstract ：
The sun gear in a planetary gearbox is prone to generate tooth crack due to its much more severe load conditions than other gears. The cracked sun gear will evolve into distinct tooth breakages and thus may deteriorate the operation status and even cause catastrophic loss of the whole transmission system. To avoid tooth crack induced malfunction of the planetary gearbox, the tooth crack of sun gear should be accurately identified during the early stage. Therefore, a novelty quantitative assessment methodology for tooth crack damage is proposed, which is a mathematical model for crack propagation of the sun gear in planetary gearboxes based on vibration acceleration signal. Firstly, the quantitative relationship between the crack propagation parameters along the gear thickness and width directions and the time-varying mesh stiffness is analytically formulated. The analytical time-varying mesh stiffness formulation is incorporated into a translational-torsional dynamic model to reveal the effects of crack propagation on the vibration signal of internal and external meshing pairs in the planetary gearbox. Secondly, a quantitative mapping function is established by taking the cracked section area as the variable and the residual of the summed envelope spectrum amplitude of the vibration acceleration signal as the assessment index. Finally, a numerical simulation as well as an experimental test is conducted and compared to verify the correctness of the proposed assessment methodology. We believe that the established model and the corresponding index provide a physically intuitive yet mathematically quantitative reference for diagnosing tooth crack in planetary gearboxes.
