摘　　要：本文通过密封胶筒单轴拉伸实验获得封隔器密封胶筒的应力应变数据,并在Origin中拟合Yeoh应变能函数中的材料常数。实验时,分边胶筒和中胶筒两种试样类型,每个试样测量2组数据,共4组数据。分别比较两种类型的材料常数,最终得到封隔器边胶筒和中间胶筒材料常数的拟合结果。The stress-strain curve of the packer seal rubber cylinder material is obtained by uniaxial tensile test in this paper, and the material constant of the Yeoh model is fitted in Origin. Two kinds of samples are tested, the side and intermediate cylinder, and two sets of figures are measured for each sample, totally 4 sets of data are obtained. Finally, by comparing the material constants for each sample respectively, the fitting results of the side and middle cylinder are obtained.
