Abstract ：
This article proposes a composite buffer based on two characteristics: porous throttling and damping energy dissipation of entangled metal wire material (EMWM). A series of quasi-static tests and low-speed impact tests were carried out to analyze its stiffness and damping characteristics. The filling degrees of cushioning force curves and energy absorption rate were proposed as quantitative evaluation indicators for the composite buffer under low-speed impact. Test results showed that the stiffness and damping of the composite buffer layer increase with the increasing density of the EMWM damping layer under quasi-static conditions, but the static loss factor fluctuates. Under low-speed impact load, the composite buffer demonstrates stable force output, with an energy absorption rate above 85% and favourable filling degrees. This work provides a practical reference for its engineering application.

Abstract ：
In the present work, a novel entangled metallic wire material (EMWM) with good mechanical properties and electrical conductivity was developed by using beryllium bronze alloy wire as raw material. A series of thermalmechanical-electrical coupling tests were carried out to investigate the mechanical properties (average stiffness, loss factor) and electrical conductivity of beryllium bronze alloy entangled metallic wire material (QBe2-EMWM) and austenitic stainless steel entangled metallic wire material (304-EMWM). The effect of the density and ambient temperature on mechanical performances and resistance properties of EMWM were analyzed in detail. It is found that the mechanical properties of QBe2-EMWM are similar to those of austenitic stainless steel entangled metallic wire material (304-EMWM). The electrical resistance of EMWM decreases with the increase of density. Moreover, the electrical resistance of QBe2-EMWM is significantly lower than 304-EMWM and is only 5 % of 304-EMWM. In the aspect of theoretical modeling, based on a cube unit-cell approach, a simplified electrical resistor network was derived from modeling low-frequency current flow through the EMWM. Considering the influence of ambient temperature, the simplified resistor network model was modified by referring to the temperature term of the Johnson -Cook model, and then the conductivity model considering temperature effect for EMWM was established. The accuracy of the theoretical electrical model of EMWM was verified by comparing the calculated results with the experimental data. The results show that the proposed model can adequately predict the electrical conductivity characteristics of EMWM under different temperatures.

Abstract ：
Strong impact does serious harm to the military industries so it is necessary to choose reasonable cushioning material and design effective buffers to prevent the impact of equipment. Based on the capillary property entangled porous metallic wire materials (EPMWM), this paper designed a composite buffer which uses EPMWM and viscous fluid as cushioning materials under the low-speed impact of the recoil force device of weapon equipment (such as artillery, mortar, etc.). Combined with the capillary model, porosity, hydraulic diameter, maximum pore diameter and pore distribution were used to characterize the pore structure characteristics of EPMWM. The calculation model of the damping force of the composite buffer was established. The low-speed impact test of the composite buffer was conducted. The parameters of the buffer under low-speed impact were identified according to the model, and the nonlinear model of damping force was obtained. The test results show that the composite buffer with EPMWM and viscous fluid can absorb the impact energy from the recoil movement effectively, and provide a new method for the buffer design of weapon equipment (such as artillery, mortar, etc.).

Abstract ：
This work is devoted to investigate the mechanical properties of entangled metallic wire material-silicone rubber composites (EMWM-SRC) sandwich structures. The core material involves the infiltration of silicone rubber (SR) into the pores of entangled metallic wire material (EMWM) through vacuum compression. Low-velocity impact tests were conducted to compare dynamic responses and energy absorption characteristics. Additionally, visual observation and computerized tomography scans were employed to characterize the damage mechanisms. It was observed that the sandwich structures did not perforate at 40–100 J impact energies, demonstrating outstanding energy absorption (97.5 %). Further explorations were conducted to explore the influence of EMWM density, wire diameter, and facesheet thickness. The results revealed that an increase in matrix density and wire diameter enhances the sandwich structure's impacts resistance but was accompanied by a decrease in energy absorption capacity. Notably, the energy absorption efficiency of the proposed sandwich structures consistently remains at a high level (88 %). Furthermore, facesheet thickness was identified as a significant factor affecting the sandwich structure. Finally, the superiority of the EMWM-SRC sandwich structure in enhancing impact resistance was validated by comparing it with individual EMWM and SR sandwich structures. These findings of this work offer valuable guidance for designing novel sandwich structures with excellent impact resistance. © 2024 Elsevier Ltd

Abstract ：
This paper investigates the free vibration, buckling and dynamic stability of spinning bi-directional functional gradient materials (BDFGMs) conical shells. The material properties vary along the thickness and axial direction. The dynamics model is established based on the first-order shear deformation theory and the governing equations and boundary conditions of the conical shell are derived employing Hamilton's principle. Subsequently, the differential quadrature (DQ) method is employed to discretize the governing equations into an algebraic system of equations for solving and analyzing the free vibration characteristics of the conical shell. The theoretical model's accuracy and the solution method's reliability are rigorously verified. The effects of temperature, functional gradient index, and rotation on the vibration characteristics, traveling wave vibration and critical speed of the conical shell in a thermal environment are systematically explored through numerical analysis. The results indicate that both the material gradient index and temperature increase lead to a decrease in the shell's natural frequency. For the spinning BDFGMs shell, elevated temperature causes the occurrence of trailing wave vibration to advance to the critical speed. Centrifugal force emerges as the primary factor influencing the critical buckling load and unstable region variation of the spinning shell.

Abstract ：
High stiffness and superior energy consumption have consistently been primary research focuses in the field of damping materials. Hence, this work presented an innovative interpenetrating phase composite (IPC) crafted from wound elastic entangled metallic porous material and silicone rubber. The proposed composite effectively integrates the unique properties of the original materials, showcasing a seamless blend. Dynamic experimental tests were conducted to analyze the dynamic compression mechanical behavior of the composites, revealing that the composites exhibit excellent energy consumption capabilities and elevated stiffness characteristics. The improvement in both stiffness and damping characteristics is attributed to the addition of silicone rubber, which solidifies the structure of the composites. The introduction of interfacial friction results from maintaining compression, sliding, and other frictional interactions among the original spiral coils. Notably, the composites also display exceptional fatigue resistance. Overall, this work demonstrates the potential to concurrently achieve enhanced stiffness and superior energy consumption through the use of entangled metallic porous material and silicone rubber. © 2024 Elsevier Ltd

Abstract ：
Metal rubber component (MRC) is commonly used in special work conditions such as high temperature/corrosive environments primarily due to its excellent vibration damping/insulation properties. But in special work conditions for a long time, the performance of MRC will deteriorate to a failure to meet the work requirements. Therefore, it is imperative to enhance the performance of MRC and study its performance degradation in special work conditions. In this paper, pickling, silanization and pickle-silanization surface treatments for metal rubber components (MRCs) were carried out. The properties of MRCs after surface treatment under static compression and full immersion corrosive test were studied, and a remaining service life prediction model of MRCs under corrosion condition was established. Compared with MRC without surface treatment (U-MRC), the performance degradation degree of several MRCs was evaluated based on four physical and mechanical parameters - the amplitude of variation in height, average stiffness, energy dissipation, and loss factor. The results indicated that MRCs exhibited different degrees of performance degradation. Among them, pickling-silanized MRC (PS-MRC) has the best corrosion resistance. The stiffness variation amplitude must be nearly 8% smaller than that of UMRC, and the energy consumption variation amplitude is about 12% smaller than that of U-MRC.

Abstract ：
Composite materials exhibit the impressive high energy consumption and impact resistance, which cannot be attained by employing conventional single materials. Along these lines, a novel entangled metallic wire mesh-silicone rubber composites (EMWM-SRC) was proposed by compressing SR into the pores of EMWM through vacuum infiltration. Quasistatic tests were conducted at various temperatures. Additionally, a comprehensive analysis of the impact velocity, matrix density, wire diameter, and anisotropy of EMWM-SRC under low -velocity impact was performed. The results revealed that the composites maintain high stability up to 300 C. Compared to traditional EMWM, the proposed composites exhibited higher loss factor, particularly with a significant enhanced in tangent modulus. The low -velocity impact results demonstrated that EMWM-SRC exhibited superior energy absorption capabilities, which was attributed to increased friction between the spiral coils and enhanced interface friction between the EMWM and SR. Notably, EMWM-SRC with different matrix densities exhibited energy absorption efficiencies exceeding 90% at an impact velocity of 3.5 m/s. Furthermore, the effects of impact velocity, wire diameter, and anisotropy on the impact response of composites were discussed in detail. Additionally, a description of the energy consumption properties was explored from the perspective of wire deformation mechanics. Overall, the proposed composites possess significant potential as impact resistant elements with high energy absorption capacity.

Abstract ：
The ship base is a structure that connects the equipment to the hull and may play a role in restraining and isolating the dynamic load. Adding damping on the base to improve the vibration isolation performance is an important measure to control ship vibration. In this research, the energy transfer route and vector cloud of the ship base were analyzed employing the power flow theory, and then the placement of the particle damper was determined. Through the discrete optimization of different particle parameters including the particle material, diameter and filling rate, the best vibration reduction effect was acquired. The simulation and experiment results show that the particle damping has obvious damping effect, and the steel particle has better damping effect than the lead particle and the aluminum particle. The change of particle filling rate influences the vibration characteristics, and the best effect is achieved when the filling rate is 82%. The vibration reduction performance relies strongly on particle diameters, and they all exert obvious vibration suppression effect at the peak acceleration admittance. The proposed discrete optimization strategy effectively saves experiment cost, and the presented particle damper may be traded as an optional scheme in vibration reduce treatment of ship base. © 2024
