Influence of Tooth Surface Geometry on Bending Fatigue Life of Face Gear by Yan Hongzhi, Wen Guangxu, Li Chao, Zhou Tengfei

“…Based on the coordinate transformation and meshing theory,the tooth surface equation of face gear is deduced.The finite element model of the different parameters（pressure angle,modulus）of face gear transmission is built,the influence of tooth face parameters on tooth root bending stresses,contact area and the distribution rule of bending stresses along the direction of tooth height and width are analyzed.Based on modified local stress-strain method,the fatigue crack initiation life in different roughness of grinding and milling tooth face is calculated.And the fatigue crack propagation life is predicted with damage tolerant design method.The results prove that the pressure angle has a great influence on the tooth face bending fatigue life,especially for the crack initiation life.A larger pressure angle is helpful to improve the tooth face bending fatigue comprehensive life.In addition,grinding method is more conducive to improve the tooth face bending fatigue life than milling method.This study provides a basis for the anti-fatigue design of face gear.…”

Discrete Element Simulation of Conical Pick’s Coal Cutting Process under Different Cutting Parameters by Jinxia Liu, Chao Ma, Qingliang Zeng, Kuidong Gao

“…From the results of the simulation tests, it can be concluded that the fragmentation of coal particles appears in a compacted, squeezed, and crumbling state in coal cutting process; the traction speed has the greatest impact on the conical pick’s cutting force and cutting force fluctuation and the influence of drum angular velocity and installation angle reduce in turn; the force and force fluctuation tend to decrease and obviously increase, respectively, with the increase of drum angular velocity and traction speed; and they will reach the minimum when the pick’s installation angle is 45° under certain traction speed and drum angular velocity.…”

Investigation of Anisotropic Permeability and Porosity of CJRM considering Different Confinement Loading Pressures by Zhiming Chao, Guotao Ma, Xiewen Hu, Yuzhe Zhu

“…In the first loading phase of confinement pressure, the impacts of confinement pressure on the anisotropic permeability of artificial CJRM, porosity, and the major and minor principle permeability coefficients (PPCs) are significant, while in the following stages of confinement pressure loading and unloading, the change of them is small, with stable value. Permeability of artificial CJRM gradually increases with rise of columnar dip angle, and the permeability anisotropy of artificial CJRM under low confinement pressure is higher than that under low confinement pressure.…”
