利用模拟装置实现了卡瓦与套管在地面上的实验，使用电测的方法测量胀卡时套管外表面的应变．由实验数据获得计算网格节点处的应变，同时利用单位咬合力作用套管的有限元结果进行数值法计算，获得卡瓦各咬合齿对套管咬合力的分布，为卡瓦的优化设计提供了可靠数据．
The simulation device was used to realize the experiment of slip and casing on the ground. The electrical measurement method was used to measure the strain on the outer surface of the casing during expansion. From the experimental data, the strain at the node of the grid is calculated. At the same time, the numerical results are used to calculate the biaxial force of the binging teeth by the unit bite force, which is provided for the optimal design of the kava Reliable data.
