针对油膜轴承巴氏合金ZChSnSb11-6在工作过程中出现的蠕变变形,提出了巴氏合金蠕变实验方法并对其进行了蠕变实验,获得了ZChSnSb11-6的蠕变特征,并与ZChSnSb8-4进行了对比分析.利用金相显微镜分析了蠕变对ZChSnSb1 1-6显微结构的影响.通过计算应力相关指数,明确了ZChSnSb1 1-6蠕变系数和应力的关系,并基于通用Graham蠕变方程建立了65℃下ZChSnSb1 1-6蠕变模型,外推得出了65℃时多组ZChSnSb1 1-6不同应力作用下的蠕变曲线.同时基于ANSYS对ZChSnSb1 1-6试件进行的有限元数值模拟,验证了ANSYS用于计算ZChSnSb11-6蠕变变形的可行性与准确性,为研究巴氏合金蠕变寿命提供了实验数据和理论支持.
