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 ：
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 ：
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 ：
The accuracy of five-axis hybrid machining equipment is one of the key indicators for evaluating its performance, and error modeling is a prerequisite for achieving accuracy synthesis and kinematic calibration. However, the current error modeling methods mainly focus on the parallel spindle head, while neglecting error sources arising from the series modules. Using such an incomplete error model for accuracy synthesis and kinematic calibration can result in suboptimal accuracy performance of the entire machine. This study focuses on a 2UPR&2RPS-XY type five-axis hybrid machine tool, considers the error influence of the serial sliding gantry module, and proposes a comprehensive error modeling method. Firstly, the error models for the fixed base-tool (2UPR&2RPS parallel spindle head) and fixed base-workpiece (X–Y sliding gantry module) are established using screw theory. Secondly, based on the structural characteristics of the machine tool, an integrated error model is developed. Next, 360 trajectory points are selected from a circular path and substituted into the established error model to obtain the roundness error of the five-axis hybrid machine tool under this trajectory. Finally, experimental validation of the proposed integrated error modeling method is conducted using a double ball bar. © The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd. 2024.

Abstract ：
As the core module of serial-parallel hybrid machining equipment, the driving characteristics of parallel manipulators are crucial to overall system performance. A set of index is proposed to evaluate the driving characteristics of a Z4 redundantly actuated parallel manipulators. Based on the proposed indices, the task workspace is optimized and the servo torques are predicted. First, the inverse kinematics of a Z4 parallel manipulator is derived with closed-loop vector method to construct a nondimensional Jacobian matrix, which is used to evaluate kinematic isotropy. Second, a rigid-body dynamic model is established by using Lagrange method, based on which a minimum 2-norm is formulated to allocate driving forces between different limbs. By selecting the tooltip as a reference point, a set of isotropy index is defined in terms of acceleration, velocity, and dynamic cutting force as well as driving torque. Finally, the optimum task workspace and servo torques are determined based on the proposed indices. A simple experimental test is carried out to validate the selected servo-motors meet the serving requirements. © 2024 Chinese Mechanical Engineering Society. All rights reserved.

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.
