油浸式电抗器用阻尼橡胶材料压缩阻尼特性与本构模型

通过对油浸式电抗器器身-油箱间阻尼橡胶材料进行轴向压缩滞回性能试验，研究了其阻尼特性；依据实验数据并结合ABAQUS数值模拟结果，校正了适用于油浸式电抗器器身-油箱间阻尼橡胶材料的Mooney-Rivlin和Yeoh本构模型参数。结果表明，相比普通抗振橡胶试件，丁腈橡胶试件的轴向压缩刚度更大，滞回曲线更饱满，耗能能力更强；Mooney-Rivlin模型和Yeoh模型均适用于NBR试件的小变形和大变形行为，其中Mooney-Rivlin模型参数和Yeoh模型参数计算结果最大误差分别为-11.31%和-12.21%。

Compressive damping characteristic and constitutive model of damping rubber material for oil immersed shunt reactor

The damping characteristics of damping rubber material between oil immersed shunt reactor body and oil tank were studied by axial compression hysteresis test and the Mooney-Rivlin constitutive model parameters and Yeoh constitutive model parameters applicable to the damping rubber material between the oil immersed shunt reactor body and the oil tank were corrected according to the experimental data and the ABAQUS numerical simulation results. The results showed that the axial compression stiffness, hysteretic curve and energy dissipation capacity of NBR specimens were higher than those of ordinary anti-vibration rubber specimens; Mooney-Rivlin model and Yeoh model were applicable to the small deformation and large deformation behavior of NBR specimens, and the maximum errors of Mooney-Rivlin model parameters and Yeoh model parameters were -11.31% and -12.21% respectively.
