Study on the mechanical properties of a type of spherical bearing

Yang Yingfang, Zhang Yan, Ju Jinsan

Journal of Theoretical and Applied Mechanics

2021

Vol. 59 nr 4

539--550

The spherical bearing is widely used in highways, bridges and long-span structures. In order to study mechanical properties of a large-scale spherical bearing, a full-scale finite element model of the spherical bearing was established by using ABAQUS software, and the mechanical properties of the spherical bearing under four working conditions were simulated respectively when the upper bearing plate had different inclination angles. The ultimate bearing capacity of the spherical bearing under vertical tension was analyzed emphatically. The research results show that, in practical applications, the change in bearing capacity caused by the inclination angle of the upper bearing plate should be considered, and the wedge-shaped part should be strengthened.

Zastosowanie metody elementów skończonych w analizie numerycznej łożysk tocznych wieńcowych

Krynke M.

Zeszyty Naukowe. Quality. Production. Improvement

2017

No. 2 (7)

71--80

W artykule przedstawiono metodykę budowy modeli MES łożysk wieńcowych. Zaproponowano zalecenia dotyczące sposobu modelowania kontaktu między elementami tocznymi a bieżniami. Uwzględniono zagadnienia związane z odpowiednim podziałem pierścieni łożyska na elementy skończone, sposób modelowania śrub mocujących łożysko do struktur zabudowy, charakterystyki materiałów. Przeprowadzone analizy zostały oparte na podstawie systemu FEMAP.

Interia effect in the squeeze film of a couple-stress fluid in biological bearings

Walicki E., Walicka A.

Applied Mechanics and Engineering

1999

Vol. 4, no 2

363-373

Couple-stresses affect lubrication problem when additives are used or lubricant contains long-chain molecules. Such couple-stresses may have a considerable effect on the behaviour of bearings in practice. The influence of couple-stress and lubricant inertia on mechanical parameters of the curvilinear thrust bearing with squeeze film is considered. The simulation of the squeeze-film behaviour of a human joint modelled as a spherical bearing is discusses as an example. It is shown that the influence of couple-stresses on the characteristics of the discussed bearing is considerable but the inertia effect is significant and not negligible. Both the effects - couple-stress and inertia - provide an enhancement in the pressure distribution and in the load-carrying capacity.
