    Optimization Design of Low Drag Torque Parameters of High-speed Wet Clutches by Wang Yuxi, Zhao Junsheng, Li Xueming, Gao Weidong, Gong Ke

    Published 2024-03-01
    “…In order to reduce the drag torque under high speed conditions, the equivalent radius is introduced into the traditional low speed torque model of a wet clutch with track vehicle, and the calculation model of the drag torque with radial groove is derived. An optimization design model is established with 3 working condition parameters of the clutch and 5 structural parameters of the friction plate as design variables, and the minimum drag torque as the optimization objective. …”

    SIMULATION AND EXPERIMENTAL STUDY ON THE STATIC STIFFNESS OF HIGH SPEED MOTORIZED SPINDLE by CUI FangYuan, LI Yan, YU JiaYi, TANG AoFei, LI PengYang, HAN LiLi

    Published 2017-01-01
    “…The static stiffness of the spindle is an important index to evaluate the static characteristics of the motorized spindle,which is essential to ensure the machining accuracy of precision CNC machine tools.Based on the calculation formulas of cutting force under typical conditions and those of radial stiffness of angular contact ball bearing,the axial deformation in front of the spindle,as well as the static stiffness in the specified condition,were obtained through the 3D finite element model of rotor-bearing system.The static stiffness test was performed on the experimental platform.By comparing the simulation results and the experimental results,the validity of the finite element model was indirectly verified.Based on the reliable finite element model,the variations of the static stiffness of the spindle with the preloads of the front and rear bearing groups were gained.…”

    A perturbative approach to complexity during shearing, dissipative collapse by Kevin Reddy, Megan Govender

    Published 2025-01-01
    “…The complexity for the initially static configuration is driven solely by the anisotropy and grows as the difference in the radial and tangential stresses grow. As the star loses equilibrium and transits into a dissipative collapse phase, the dynamical complexity is enhanced by contributions from the anisotropy and density inhomogeneity. …”

    MODELING AND ANALYSIS OF LOCAL FAILURE GRADUAL DYNAMICS OF ROLLING BEARING INNER RING (MT) by SHANG ZhiWu, PANG HaiYu, GAO MaoSheng, LIU JingYu

    Published 2023-01-01
    “…From the objective reality and irregularity of the inner ring′s actual fault shape, the displacement excitation function is introduced to qualitatively analyze the gradual change of the ball position when it passes through the fault area, and a random number sequence is used to list the characteristics of the irregularity of the bottom. Considering the radial load of the bearing and the slipping phenomenon of the balls through the fault area, a bearing inner ring dynamics model of the local gradient fault is established, and the accuracy of the model is verified by comparing and analyzing the characteristic frequency values of the fault under different rotational conditions.…”
