我们描述了一个分析模型，用于研究不同配置的相对圆形压缩机沿压缩轴的应力行为，并应用于弹性学。该方法基于一个假设，即轴上任何一点的轴向应力是由两端边界条件导出的应力的各个分量的叠加。根据该模型确定的轴向应力行为允许对某些随深度变化的应力弹性图进行修正。实验结果证实了模型的正确性。
We describe an analytical model to study the behavior of stress along the compression axis for different configurations of opposing circular compressors, as applied to elastography. The method is based on a hypothesis that the axial stress at any point on the axis is the superposition of the individual components of the stresses derived from the boundary conditions at either end. The determination of the axial stress behavior according to the model permits the correction of certain elastograms for depth-dependent stress. Experimental results have been presented to corroborate the model.
