    Finite Element Simulation Analysis for Dynamic Meshing Force of Straight Tooth Face Gear by Cao Maopeng, Tang Jinyuan, Lei Duncai

    Published 2015-01-01
    “…Analysis of the dynamic meshing force of face gear is the important content in the design of face gear drive with high quality.Based on the secondary development of CATIA and the principle of gear machining,the 3Dgeometric modeling of face gear for finite element analysis is obtained.Based on basic theory of contact dynamics,the reasonable finite element analysis model is built and the reasonable parameters are determined.The finite element simulation analysis and study of the dynamic meshing of face gear are carried out by using the ABAQUS,the variation law of the tooth surface contact force and the tooth root bending stress of face gear in the process of continuous mesh and the association law of the among the speed,load and tooth surface dynamic meshing are obtained.It will be provide some reference value for dynamic performance analysis of high-performance face gear drive.…”

    Simulation Analysis of the Influence of Tooth Surface Pit Morphology on the Dynamics Performance of Face Gear Mesh by He Guoqi, Deng Shujie, He Ying, Yan Hongzhi, Sun Neng, Wang Qilei

    Published 2016-01-01
    “…The three dimensional solid model of the face gear with different pit morphology and the simulation model of the face gear transmission system of the pit morphology are established,through the contact collision algorithm of multi- body dynamics,the change regularity of meshing force and output speed of the different pit morphology face gear transmission under certain condition is analyzed.The results show that the influence of the circular pit morphology on the transmission system meshing force is the smallest,the value of transmission error is the lowest,so the transmission stability is optimal.And the experimental conclusion is consistent with the simulation results,the correctness of the simulation is verified.A reasonable basis of oil- lack lubrication model of face gear with pit morphology in the future is provided by the results.…”

    Research and Application of Rock Burst Hazard Assessment of the Working Face Based on the CF-TOPSIS Method by Feng Zhu, Haowei Song, Bingxiang Huang, Binxin Hu, Siqi Li, Guangdong Song, Hua Zhang, Tongyu Liu, Fuwu Ma

    Published 2023-01-01
    “…Based on these, the CRITIC objective weight algorithm model is established, and FAHP is used to optimize weighting factors to make the index weight of rock burst more reasonable, thus enhancing the accuracy of hazard assessment for working faces. Results from engineering examples show that the prediction results combined with field drill cutting methods and microseismic monitoring data verify the accuracy of the proposed method, indicating its feasibility and effectiveness in predicting rock burst hazard in underground coal mines.…”
