The bluff body is integral to a flow-induced vibration (FIV) energy harvesting system, with its aerodynamic characteristics tunable via a biomimetic metasurface. This paper proposes a FIV energy harvester utilizing a bioinspired metasurface to enhance energy harvesting performance. The mathematical model of the proposed FIV energy harvester is developed. Lift and drag forces are determined through numerical simulation using COMSOL. Prototypes of the FIV energy harvester with bioinspired metasurfaces are fabricated and validated in a wind tunnel experimental system. numerical and experimental results demonstrate that the performance of FIV energy harvesters can be either suppressed or enhanced by employing a bluff body with a bioinspired metasurface. The operation bandwidth of the FIV energy harvester with a straight striped metasurface bluff body increased by nearly 277% compared to the traditional smooth body, providing a practical method for harnessing wind energy across diverse natural environments and adapting effectively to fluctuating wind conditions. © 2025, The Authors.

Electro-hydraulic proportional directional valves are widely used in precision engineering fields, where their operational stability and reliability are critical to the performance of hydraulic systems. However, high pressure and high-frequency responses significantly affect the hydraulic forces acting on the spool, while deformations caused by pressure and thermal loads may further compromise its performance. Therefore, analyzing and compensating for hydraulic forces, as well as investigating the deformation behavior of the spool under pressure and thermal loads, are essential for enhancing its stability and reliability. Based on CFD numerical calculation methods and fluid-thermal-solid multi-physics coupling technology, the study systematically investigates the characteristics of hydraulic forces and the deformation behavior of the spool. First, Fluent was used to simulate the fluid domain under steady-state and transient conditions, obtaining pressure and velocity contour maps, flow rate curves, and the hydraulic forces acting on the spool in different structural cavities formed by the valve sleeve and spool at different valve opening degrees. The analysis identified the best cavity configuration for compensating hydraulic forces between the valve sleeve and spool. Secondly, orthogonal experimental design and numerical simulation were conducted for the arc-shaped transition cavity, followed by multi-objective optimization using a genetic algorithm. The optimized structure reduced the steady-state hydraulic force to varying extents, with a maximum reduction of 23%. Finally, the fluid-thermal-solid multi-physics coupling technology was employed, selecting the optimal structure with the best hydraulic force compensation effect for analysis. The results show that the deformation of the spool in both radial directions increase as the valve opening increases. At a valve opening of 1 mm, the maximum radial deformation in the Z direction is 7.0471 μm. Additionally, with

In order to solve the problem that minimum control strategy of equivalent fuel consumption for plug-in hybrid electric vehicles (PHEVs) is not effective, an ECMS energy management strategy based on improved annealing algorithm was designed. Firstly, based on the traditional control model, the optimized PID equivalent factor control model is constructed. In order to solve the problem of overfitting when optimizing the traditional annealing algorithm (SA), tempering link and memory search function were added to the algorithm, and the improved algorithm was used to optimize the PID equivalent factor, and the vehicle dynamics simulation was carried out in MATLAB/SIMULINK environment. The results show that: Under the Worldwide Light-duty Test Cycle (WLTC) conditions, compared with the rule-based logical threshold control strategy and the pre-optimized ECMS strategy, the optimized ECMS strategy increased the fuel saving rate by 18.49% and 3.28%, respectively. Under the New European Driving Cycle (NEDC) conditions, compared with the rule-based logical threshold control strategy and the pre-optimized ECMS strategy, the fuel saving rate is increased by 20.20% and 2.61%, respectively. The proposed model effectively reduces fuel consumption and has good robustness. © 2023 SPIE.

This paper attempts to use a simple and practical method based on the finite element theory for the optimal structural design of machine tool bed. The higher is the natural frequency of structure, the better are static and dynamic structural stiffness. Dynamics finite element model of CA6136 machine tool bed has been established with the finite element analytic technique in order to improve the dynamic characteristics. Then, two improved bed design schemes based on unit structure (US) are presented and analyzed by comparison using natural frequency and the total mass of structure as target. The simulation results indicate that the method is simple, effective and feasible. The method also can be applied to other dynamic structural design. © (2014) Trans Tech Publications, Switzerland.
