Research on the diameter of bidirectional double-loop networks G（N;±1,±s） in cartesian coordinates by LIU Hui, FANG Mu-yun, ZHENG Xiao, HANG Ting-ting

“…A new method to research the diameter of the bidirectional double-loop networks G（N;±1,±s） was presented based on cartesian coordinates.Using this method,the limited bound of diameter of the bidirectional double-loop net-works G（N;±1,±s） presented by Boesch and Wang was certified and the limited bound of average diameter was given.At last,the simulation of the graph of bidirectional double-loop networks G（N;±1,±s） for any given N,s was given.Com-pared whith L-shaped tile simulation which can not be used in the bidirectional double-loop networks directly,this method improved the research level of the bidirectional double-loop networks greatly.…”

RESEARCH ON SOLUTION METHOD OF CONTACT STIFFNESS OF CURVIC COUPLINGS CONSIDERING TOOTH SURFACE ROUGHNESS by MA Wu, WANG AiLun, WANG Hai, YANG ZhengLie

“…Aiming at the problem that the contact stiffness analysis method of curvic couplings can not consider the contact interface microscopic morphology,an analytical model of the contact interface stiffness was proposed.Through the stress analysis and stiffness transformation,the general model of curvic couplings contact interface stiffness was obtained,and the GW rough surface model was brought into it to obtain the specific curvic couplings contact interface stiffness formula based on the GW rough surface model.Finally,the analytical model results were compared with finite element results.The effect of surface topography on the contact stiffness of curvic couplings was obtained,and the relationship between the normal contact stiffness and the tangential contact stiffness with the preload and tangential force were obtained.The research shows that the analytical model matches well with the finite element results,which proves the rationality of the analytical model and provides a theoretical reference for the preload force and torque design of the rotors with curvic couplings.…”
