Mechanical Behavior Evolution and Damage Characterization of Coal under Different Cyclic Engineering Loading by Huajun Wang, Jian Li

“…It is found that LURR is an effective parameter to evaluate the damage of coaly rock under cyclic loading and is also useful in distinguishing different deformation mechanism at different loading stages. The results also show that the damage of coal can initiate at the early stage of cyclic loading at a low loading frequency; however, the increase in frequency of cyclic loading can delay the damage time, requiring a relatively higher level of peak cyclic stress amplitude.…”

Design Method of Crank-rocker Mechanism based on Maximum Value of Minimum Transmission Angle by Chen Haiwen, Wang Zhong, Zhao Fei

“…Under the conditions of giving the length of the rocker CD,swinging angle φ and advance-to return-time ratio K（extreme position angle θ）,in order to design crank-rocker mechanism with the maximum value of minimum transmission angle γmin,the supplementary angle β（be used to determine the position angle of the rotation center A of crank） is introduced,the function relation of minimum transmission angle γminand the supplementary angle β is established.Then the maximum value of minimum transmission angle γmincan be obtained by utilizing procedure of Matlab.At the same time,in view of the different K value,the mechanism of type selection is classified.Then,points out the typeⅠ and Ⅱmechanism can be used to design and typeⅠ mechanism is better in force-passing property when K ∈（1,3）.When K∈[3,+ ∞),if type Ⅱ mechanism is used to carry on the design,which will not be able to meet the requirement of the rocker swinging angle,if typeⅠ mechanism is used,which has low efficiency and is not conductive to transmission of the mechanism.…”

Research on Stepless Speed Change Mechanism of Variable Diameter Pulley and Planetary Compound Transmission by Chuang Yan, Aiping Song, Jianzhou Pan, Ning Mei

“…Multi-channel transmission and power convergence can be realized through the combination of variable-diameter pulley transmission and planetary gear transmission, and the ratio of power convergence can be adjusted through the free ratio of two input speeds of planetary differential gear train. The mechanism has the characteristics of simple structure, high transmission power, high efficiency transmission and stable operation.…”

Near-orientation deformation banding formation mechanism of Al-Mg-Mn-Er alloy by Hongfu Yang, Mengnie Li, Yaru Wu, Shumeng Lu, Rensong Huang, Shanju Zheng, Xiaohong Yuan, Yonghua Duan

“…When two related slip systems are activated and intersect, lattice rotation occurs, and the orientation deviation of the grains gradually increases, resulting in grain splitting and forming a banded structure. This mechanism provides a preliminary theory for regulating Σ3 grain boundaries and introduces a novel method to enhance the performance of aluminum alloys.…”
