摘　　要：以拉伸强度为特性指标,对轴承用聚酰亚胺保持架材料进行加速老化试验,根据试验结果构建两步法和整体法2种模型,2种模型相互验证表明,轴承用聚酰亚胺保持架材料在室温存储下的寿命至少为37年。The accelerated aging test of polyimide cage materials for bearings is carried out with tensile strength as characteristic index.The two-step and integral models are established based on test results.The mutual validation of two models shows that the storage life of polyimide cage materials for bearings under room temperature is at least 37 years old.
