摘　　要：芳纶/聚四氟乙烯织物自润滑衬垫是航空自润滑关节轴承的功能件,在相关研究与分析的计算中,需要精确设置其材料的宏观力学性能参数。为此,通过细观构型计算获得芳纶/聚四氟乙烯纤维织物宏观力学性能参数。依据斜纹织物结构,给出了修正的RVE细观模型,并建立了相应的弹性性能分析模型。应用数值模拟方法和解析法,分别计算了织物衬垫的力学性能参数,通过试验数据比较,对模型与计算获得的力学性能参数的有效性进行了验证。结果表明,给出的参数化细观结构模型可以用于织物衬垫力学性能计算,获得宏观的力学性能参数。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 purpose 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.
