    Analysis of Temperature Rise Characteristics and Fatigue Damage Degree of ACSR Broken Strand

    Jun Zhang1, Xiaobin Li1, Long Zhao2,*, Zixin Li1, Shuo Wang1, Pan Yao1, Pengfei Dai2

    Energy Engineering, Vol.120, No.3, pp. 617-631, 2023, DOI:10.32604/ee.2022.024855

    Abstract In this paper, the research on ACSR temperature of broken strand and fatigue damage after broken strand is carried out. Conduct modeling and Analysis on the conductor through Ansoft Maxwell software. The distribution of magnetic force lines in the cross section of the conductor after strand breaking and the temperature change law of the conductor with the number of broken strands are analyzed. A model based on electromagnetic theory is established to analyze the distribution of magnetic lines of force in the cross section of the conductor after strand breaking and the temperature variation law… More >

    Steady-State Temperature Rise in Coated Halfspaces and Halfplanes

    Michael J. Rodgers1, Leon M. Keer, Herbert S. Cheng

    CMES-Computer Modeling in Engineering & Sciences, Vol.3, No.4, pp. 483-496, 2002, DOI:10.3970/cmes.2002.003.483

    Abstract The steady-state temperature rise due to frictional heating on the surface of coated halfspaces and halfplanes is described by closed form expressions in the Fourier transformed frequency domain. These frequency response functions (FRFs) include the effects of the coating and the speed of the moving heat source and apply for all Peclet number regimes. Analytical inversion of these expressions for several special cases shows the Green's functions as infinite series of images, which may be costly and slowly convergent. Also, the influence coefficients integrated from these Green's functions are not available in closed form. Applying… More >
