Abstract ：
The demand for butt welding of stainless-steel thin plates has been increasing year by year in industries such as shipbuilding, pharmaceuticals, petrochemicals, and food processing. However, during the butt welding of thin plates, the low structural rigidity causes real-time change in the gap, which complicates the ability of automated welding to achieve uniform weld seam geometry. Therefore, this paper aims to overcome the challenges of cross coupling and the sensitivity of hyperparameter selection and realize the gap-adaptive welding during the high frequency pulse arc welding process by implementing to optimize the number of trees and the minimum number of leaf nodes in the random forest model. After the optimal welding parameters are then used to train the random forest model, a gap-adaptive control platform, which take gap, weld face width, weld root width, and face reinforcement as input features and peak current, wire feed speed, and welding speed as output features, is established to enable real-time measure the gap by using a laser track sensor. The results demonstrate that under fixed and gradient gap conditions, the weld seam geometry is uniformly formed and no significant defects can be found. Under step gap conditions, gap-adaptive welding effectively prevents burn-through defects and ensures stable weld seam geometry. Furthermore, microstructural and mechanical property characterization indicates that an increase in frequency during welding effectively refines the grain size in the seam. The tensile strength values of the samples are similar and all samples fracture at the base metal.

Abstract ：
This paper explores the application of multidisciplinary design optimization to the blades in horizontal-axis wind turbines. The aerodynamics and structural performance of blades are considered in the optimization framework. In the aerodynamic discipline, class function/shape function transformation-based parameterized modeling is used to express the airfoil. The Wilson method is employed to obtain the aerodynamic shape of the blade. Computational fluid dynamics numerical simulation is performed to analyze the aerodynamics of the blade. In the structural discipline, the materials and ply lay-up design are studied. Finite element method-based modal analysis and static structural analysis are conducted to verify the structural design of the blade. A collaborative optimization framework is set up on the Isight platform, employing a genetic algorithm to find the optimal solution for the blade's aerodynamics and structural properties. In the optimization framework, the design variables refer to the length of the blade chord, twist angle, and lay-up thickness. Additionally, Kriging surrogate models are constructed to reduce the numerical simulation time required during optimization. An optimal Latin hypercube sampling method-based experimental design is employed to determine the samples used in the surrogate models. The optimized blade exhibits improved performance in both the aerodynamic and the structural disciplines.

采用环块式摩擦磨损实验研究了一种新型摩擦材料在水润滑状态下不同载荷与转速对试样摩擦学性能的影响,并对比干摩擦条件下的摩擦学性能变化,借助磨损表面形貌观察分析其磨损机理.实验结果表明:水润滑条件下,摩擦系数随着载荷的增大而减小,随着转速的提高先增加后减小;磨损率随着载荷与转速的提高都减小.相同载荷与转速下,干摩擦时磨损机理以磨粒磨损和黏着磨损为主,而水润滑条件下水形成边界润滑,磨损机理以磨粒磨损和轻微的黏着磨损为主;水润滑条件下摩擦系数和磨损率均低于干摩擦,主要是由于水起到了润滑和冷却的作用,阻止了转移膜的形成,并在材料表面形成水膜起到了边界润滑的作用.

Abstract ：
A high-quality brake material was developed by using different rare earth oxide modified resin-based brake materials and designing the composite material through an orthogonal optimization test. The effect of rare earth oxide on the properties of the resin-based brake material, such as the friction and wear, thermal decay resistance, and recovery, was explored using the constant-speed friction test, Chase friction test and worn surface morphological observation. The results show that rare earth lanthanum oxide can be added to improve the friction and wear properties of the brake material compared to cerium oxide and yttrium oxide. At 100–350°C, the friction coefficient of the developed brake material fluctuates in the range of 0.40–0.50, and the material has high friction coefficient, good thermal decay resistance and favourable wear resistance. The friction coefficient of the optimal formulation can reach the GF level, so its tribological properties are very good and better than the brake pads of automobiles at home and abroad. © 2019, © 2019 Institute of Materials, Minerals and Mining and Informa UK Limited, trading as Taylor & Francis Group.
