Abstract:

Aramid/polytetrafluoroethene fabric self-lubricating liner is one of function parts of self-lubricating spherical plain bearing, and its macroscopic mechanical properties parameters should be set up accurately in the calculation of relevant research and analysis. The research purposes is to acquire macro mechanics performance parameters of the aramid/polytetrafluoroethene fabric by the calculation of mesoscopic configuration. Based on the twill structure, the fixed RVE mesoscopic model and elastic performance analysis model had been built. The mechanics properties parameters had been calculated by numerical simulation method and analytic method. And then, comparing with experimental data, the effectiveness of the given model and the mechanics performance parameters had been verified. The study shows that the given parameterized mesoscopic structure model can be used to calculate the macro mechanical performances. Thus, the fabric liner mechanics performance can be achieved accurately.
