Authors: Zhang Bo 
Published: March 2021

Abstract
As the most important end-effector of the robot, the robot hand determines the performance of the robot to a certain extent. Therefore, the robot hand often needs high degree of flexibility and larg grasping force to complete complex and diverse tasks. However, most of the existing robot hands are usually difficult to meet the above two requirements. Aiming at this problem, a dexterous robot hand driven by tendon ropes was designed in this paper. Its thumb is a continuum flexible finger with a nickel-titanium alloy wire as the center rod, and the remaining four fingers are tendon-driven rigid fingers. This design allows the thumb to adapt to objects of various shapes, so that the entire robot hand is extremely flexible, and the rigid structure of the four fingers can provide an enough grasping force for the robot hand. In this paper, the robot hand was mechanically designed and simulated by simulation software to ensure the reliability of the design. The workspaces of fingers werecalculated by Matlab through the established DH coordinate system and kinematics model of the robot fingers. In this paper, a physical model of the robot hand was made through 3D printing technology, and thin-film pressure sensors are installed at the end of the fingers to measure the grasping force in real time. Finally, various shapes of objects were selected for the grasping operation, which verified the flexibility and enough grasping force of the robot hand.

Published: March 2021

Abstract
Radiated electromagnetic waves during the opening of the circuit breaker can be used to evaluate the arc extinguishing performance of the circuit breaker. Current research shows that the duration of electromagnetic waves is the main feature. However, the current research does not consider the influence of the type of load on the electromagnetic wave radiation during the opening process. In this paper, an experimental research platform is established, and the influence of the load type on the electromagnetic wave radiation during the opening process is studied by testing the resistance, inductance and capacitance loads. The research results show that the arcing time and visible arcing times of breaking capacitive loads are significantly greater than resistive and inductive loads.

Authors: Shi Chen , Mao Xuqiang , Shen Ke 
Published: March 2021

Abstract
To reduce the work hardening of the 8011 cast-rolled plates after multiple rolling, 8011 cold-rolled plates with a deformation of 78% were annealed at different temperatures. The influence of annealing temperatures exercise upon the microstructure, texture and earing of cold-rolled sheets was analysed by means of ODF texture analysis, EBSD technology and cup drawing test. The results show that the contents of the deformed microstructure, the recrystallized structure and the substructure change sharply annealing at 300°C, but they tend to be stable at 350°C. The starting temperature of recrystallization of 8011 cold-rolled plates is about 300°C. When cold rolled sheets were annealed at low temperatures, there were quantities of grain boundaries whose angle was small. When the annealing temperatures were higher, the small and medium angle grain boundaries of the cold rolled sheets decreased gradually. The general trend was that the small angle grain boundaries first increased and then decreased as the case of annealing temperature rise. The proportion of the small angle grain boundaries reached to the minimum value of 20.2% at 350°C. When annealing temperature is 350 °C, the lowest earing rate is 2.11%.

Abstract
Epoxy resin adhesive have many advantages that other adhesives do not have, and are widely used in various fields. At the same time, it is also a thermosetting resin with high crosslinking density. Its cured product is brittle, low impact strength, and easy to crack. These shortcomings limit the further application of epoxy resin. This article takes the plugging agent of UDMH as the starting point. Epoxy resin adhesive toughened and modified with two kinds of inorganic fillers, nano-titania and micro-alumina, were prepared and study the compatibility of modified epoxy resin adhesive with UDMH. It is found that under certain conditions, the silane coupling agent KH570 can undergo a grafting reaction with the hydroxyl groups on the surface of nano-TiO2 to improve its lipophilic and hydrophobic properties, and the effect is better than KH560, KH550; Through FT-IR, SEM, TG and other characterization methods, it is found that when the content of coupling agent is 15%, the effect of surface modification is the best. In the preparation of two kinds of inorganic filler modified epoxy adhesives, it is found that when the content of nano-TiO2 is 3%, the toughening effect is the best, and the impact strength can reach 36.78 KJ/m2; When the content of micro alumina is 60%, the toughening effect is best, and the impact strength can reach 28.43 KJ/m2. In general, the toughening effect of using nano-TiO2 is significantly better than that of alumina. In the study of the compatibility of the two kinds of filler modified epoxy resin adhesives with UDMH, it is found that when nano-titanium oxide is used as the filler, the compatibility of epoxy adhesive and UDMH is improved. However, when micro-alumina is used as the filler, the compatibility of epoxy resin adhesive and UDMH becomes worse.

Study on very-high-cycle fatigue property of 2A60 aluminum alloy
Authors: Wen Feijuan , Xing Zhiguo , Tan Chunmei , Pu Jingchen , Zhou Lei 
Published: March 2021

Abstract
During the rotation, aero-engine impeller blades are subjected to the alternating load of high frequency, low stress and small strain, so it is effortless for the impeller blades to enter the stage of very-high-cycle fatigue (VHCF). The research on the VHCF performance of 2A60 aluminum alloy is of great engineering significance to verify the reliability of the impeller in service. In this paper, the VHCF performance of 2A60 aluminum alloy is studied by fatigue life curve and fracture morphology. The results show that the fatigue properties of 2A60 aluminum alloy under different cooling conditions are different, and the VHCF properties under ethanol cooling conditions are better than those under water cooling conditions. However, under either water-cooled or ethanol-cooled conditions, the fatigue fracture mode of 2A60 aluminum alloy is single, showing a surface crack initiation mode, and the S-N curve shows a continuous downward trend without the intermediate platform. The VHCF crack originated from the stress concentration on the sample surface and the cleavage fracture occurred in the grains near the crack source in the early stage of crack initiation. The VHCF process of the sample is also the relaxation process of its residual stress.

Published: March 2021

Abstract
The formulation of quadratically consistent three-point integration scheme based on point interpolant method (PIM-QC3) is proposed for free vibration analysis of two-dimensional solids. Based on the condition with regard to nodal shape function and its derivatives for arbitrary-order approximations, PIM-QC3 is developed using point interpolant method and T6-Scheme for node selection. Thus, complex calculation of inverse matrix at every quadrature points is avoided. And the shape functions including corrected derivatives of nodal shape functions at quadrature points, adopt quadratic basis, meet the so-called differentiation of the approximation consistency as well as the discrete divergence consistency. In addition, the Kronecker delta property is possessed. Some problems for the free vibration of two-dimensional solids are employed to examine the accuracy and efficiency of the PIM-QC3. The numerical results indicate that PIM-QC3 is a very accurate, stable and highly efficient method for the structural analysis of free vibration.
