Advances in Space research 2025年

Spacecraft shields are essential for protecting spacecraft from damage caused by space debris and micrometeoroids. Depending on the source, naturally occurring impactors can reach velocities up to 72 km/s or even higher, particularly for stellar particles, presenting significant challenges for shield impact resistance. In order to enhance the debris protection performance of the Whipple shield, optimize debris cloud distribution, and improve debris kinetic energy dissipation, an SPH model incorporating eight non-spherical impactors and a Whipple shield was established and experimentally validated. This study investigates how the shape and state of the impactor, as well as the shield’s surface condition, affect the impact process using LS-DYNA. Additionally, four reinforcement designs for the Whipple shield were numerically simulated and analyzed. Results indicate that a vertical impact from a dumbbell-shaped projectile causes the most damage to the shield. The tungsten carbide coating significantly improves the kinetic energy dissipation rate of the impactor, reaching 65%, which is 137% higher than that of the traditional Whipple shield. The shot-peened shield expands the fragment cloud distribution area, effectively blocking impact fragments. Statistical analysis of fragment shape and orientation reveals a significant linear correlation between the center of mass height, the shield’s normal projected area, and the kinetic energy dissipation of non-spherical impactors. This model can predict Whipple shield damage from such impactors.

Chinese Journal of mechanical engineering 2018年第1期31卷 176-186页

Flexure-based mechanisms are widely utilized in nano manipulations. The closed-form statics and dynamics modeling is difficult due to the complex topologies, the inevitable compliance of levers, the Hertzian contact interface, etc. This paper presents the closed-form modeling of an XY nano-manipulator consisting of statically indeterminate symmetric(SIS) structures using leaf and circular flexure hinges. Theoretical analysis reveals that the lever’s compliance, the contact stiffness, and the load mass have significant influence on the static and dynamic performances of the *** are conducted to verify the effectiveness of the established models. If no piezoelectric actuator(PEA) is installed, the influence of the contact stiffness can be eliminated. Experimental results show that the estimation error on the output stiffness and first natural frequency can reach 2% and 1.7%, respectively. If PEAs are installed, the contact stiffness shows up in the models. As no effective method is currently available to measure or estimate the contact stiffness, it is impossible to precisely estimate the performance of the overall system. In this case, the established closed-form models can be utilized to calculate the bounds of the performance. The established closed-form models are widely applicable in the design and optimization of planar flexure-based mechanisms.

Abstract A friction stir processing-based method was used to repair cracks in the 2024 aluminum alloy plates. The temperature field and plastic material flow pattern were analyzed on the basis of experimental and finite element simulation results. Microstructure and tensile properties of the repaired specimens were studied. The results showed that the entire crack repairing was a solid-phase process and plastic materials tended to flow toward the shoulder center and then resulted in the repairing of cracks. Meanwhile, the coarse grain structures were refined in repaired zone （RZ）, while the grains in thermal-mechanically affected zone and heat-affected zone were elongated and driven to grow up. Meanwhile, large phases are crushed into small particles and dispersed inside the RZ. Finally, the strength of the repaired specimens can be restored dramatically and their ductility can be partially restored. After heat treatment, the tensile properties of the repaired specimens can be further enhanced.

Gd is a highly effective element for neutron shielding, but its minimal solubility promotes Gd-rich intermetallics that degrade alloy properties if not properly controlled. This study introduces an innovative approach to refine these intermetallics to a sub-micron scale and achieve a uniform distribution by leveraging the cellular boundaries formed during laser powder bed fusion. These cellular boundaries, combined with the tailored intermetallics, act as "modulators" that effectively impede plastic deformation while permitting dislocation motion, resulting in a satisfying strength-ductility synergy. The findings offer a promising direction for incorporating elements with low solubility but functional properties by tailoring intermetallics through cellular boundary engineering. © 2025 The Author(s)

In this study, TiC + TiB2 nano-ceramics reinforced high–Cr die steels were successfully prepared using aluminum-based master alloy as a carrier for the nano-ceramics. The impact of nano-ceramics on the microstructure of steels as well as the tensile properties and friction and wear properties under high temperature conditions were explored. The incorporated nano-ceramics can significantly refine the microstructure of steels, resulting in finer and more uniformly precipitated carbides, thereby effectively improving the mechanical properties of steels. Compared with unmanipulated high–Cr die steels, the high-temperature (550 °C) yield strength of high–Cr steels reinforced with 0.02 wt% nano-ceramic was increased from 963 MPa to 1274 MPa. The volume wear rate of nano-ceramics reinforced high Cr steels reached 11.9 × 10−13 m3/m, 3.4 × 10−13 m3/m, 5.6 × 10−13 m3/m and 6.3 × 10−13 m3/m under the four conditions of 400 °C-30 N-300 r/min, 550 °C-20 N-300 r/min, 550 °C-30 N-300 r/min and 550 °C-40 N-300 r/min, which were reduced by 23.7 %, 34.6 %, 34.9 % and 35.1 % respectively. These results provide a new insight into improving the high-temperature friction and wear properties of steels. © 2025 Elsevier Ltd and Techna Group S.r.l.

A parameterized dynamics analysis model of legged lander with adaptive landing gear was established. Based on the analysis model, the landing performances under various landing conditions were analyzed by the optimized Latin hypercube experimental design method. In order to improve the landing performances, a hierarchical optimization method was proposed considering the uncertainty of landing conditions. The optimization problem was divided into a higher level(hereafter the "leader") and several lower levels(hereafter the "follower"). The followers took condition?ing factors as design variables to find out the worst landing conditions, while the leader took bu er parameters as design variables to better the landing performance under worst conditions. First of all, sensitivity analysis of landing conditioning factors was carried out according to the results of experimental design. After the sensitive factors were screened out, the response surface models were established to reflect the complicated relationships between sensi?tive conditioning factors, bu er parameters and landing performance indexes. Finally, the response surface model was used for hierarchical optimization iteration to improve the computational e ciency. After selecting the optimum bu er parameters from the solution set, the dynamic model with the optimum parameters was simulated again under the same landing conditions as the simulation before. After optimization, nozzle performance against damage is improved by 5.24%, the acceleration overload is reduced by 5.74%, and the primary strut improves its performance by 21.10%.

Responding to the special needs under the context of normalized epidemic prevention and control and the aging trend of the population, this research proposes a method based on a 3D deep learning model to process laser sensor point cloud data, aiming to achieve non-contact gesture surface feature analysis for application in the field of intelligent rehabilitation of human-machine interaction hand functions. By integrating key technologies such as the collection of hand surface point clouds, local feature extraction, and abstraction and enhancement of dimensional information, this research has constructed an accurate gesture surface feature analysis system. In terms of experimental results, this research validated the superior performance of the proposed model in recognizing hand surface point clouds, with an average accuracy of 88.72%. The research findings are of significant importance for promoting the development of non-contact intelligent rehabilitation technology for hand functions and enhancing the safe and comfortable interaction methods for the elderly and rehabilitation patients.
