摘要

摘要: 利用有限元模型对自润滑织物复合材料的拉伸强度进行预测，得到了复合材料的磨损率预测模型。采用TexGen建立了自润滑织物复合材料的单胞有限元模型，利用ABAQUS对复合材料的拉伸进行了有限元模拟，最后通过实验验证了复合材料的拉伸强度。结果表明，复合材料经向模拟值与实验值差异率为6.71%，纬向差异率为5.51%，从而说明复合材料有限元模型具有较高的可靠性。从拉伸应力云图可得复合材料的拉伸强度由拉伸方向的纤维的弹性模量决定。在此基础上对自润滑织物复合材料的磨损率及摩擦磨损机制分析，建立复合材料的拉伸强度与磨损率之间的映射关系，预测模型得到的磨损率预测值与实验结果的平均差异率为8.43%，表明体积磨损率预测模型的可靠性。

Abstract: The finite element model was used to predict the tensile strength of the self-lubricating fabric composites, and the wear rate prediction model of the composites was obtained. The unit cell finite element model of self-lubricating fabric composites was established by TexGen, and ABAQUS was used to perform finite element simulation of composites stretching, the tensile strength of the composites was verified by experiments lastly. The results show that the difference rate between the simulated value of the composites in the warp direction and the experimental value is 6.71%, and the rate of difference in the weft direction is 5.51%, indicating that finite element model of the composites has high reliability. From the tensile stress cloud diagram, it can be seen that the tensile strength of the composites is determined by the elastic modulus of the fiber in the tensile direction. On this basis, analysis of the wear rate and friction and wear mechanism of self-lubricating fabric composites, the mapping relationship between the tensile strength and the wear rate of the composites was studied. The difference rate between the predicted value of the wear rate obtained by the prediction model and the experimental result is 8.43% on average, indicating reliability of the volume wear rate prediction model.
