摘要
通过对由聚四氟乙烯（ＰＴＦＥ）塑料和青铜丝弹簧所组成的复合材料轴瓦的性能进行实验测量和理论分析，建立了反映复合材料轴瓦的应力与应变关系的材料松弛模量矩阵，分析了普通ＰＴＦＥ塑料与用作轴瓦材料的ＰＴＦＥ的差别，得出了ＰＴＦＥ塑料与青铜丝复合层的蠕变及柔量矩阵。
Analyzed are the properties of the PTFE (polytetrafluoroethylene) and PTFE plastic materials bearing pad. The composite material is made of the aforementioned plastics as matrix reinforced by fine bronze elastic springs. Relaxation modulus of the material is presented. The difference between the two is studied. The results show that the complex modulus of PTFE plastic is higher than that of normal PTFE plastic. Bearing property data are also given.
