METHOD FOR CALCULATING COUPLED LUBRICATION AND DYNAMICS CHARACTERISTIC PARAMETERS OF FLANGED BEARING
Publication number: 20240264039Abstract: A method for calculating coupled lubrication and dynamics characteristic parameters of a flanged bearing includes three modules: a flanged bearing journal-trust thermal elastohydrodynamic coupled lubrication module, a flanged bearing dynamics characteristic parameter calculation module and a flanged bearing relative position feedback module. It considers the joint motion law of the journal part and the thrust part, and also considers the flow, pressure and thermal continuity conditions of the lubricant on the common boundary of the flange bearing, and finally forms the journal-thrust transient coupled lubrication analysis method of the flange bearing. On the basis, considerations are further given to the stiffness and the damping characteristics of the flanged bearing under the coupled effect, thereby achieving accurate simulation of the dynamic and the tribology performance of the flanged bearing, and solving the problem of lubrication failure of the flanged bearing.Type: ApplicationFiled: February 28, 2023Publication date: August 8, 2024Applicant: HARBIN ENGINEERING UNIVERSITYInventors: Bin ZHAO, Jiahao SHI, Xiqun LU, Wanyou LI, Hanzhang XU, Xuan MA, Xiujiang SHI, Zhijun SHUAI, Yibin GUO, Donghua WANG, Hongliang LI, Lieyi DONG -
