摘　　要：柔性随动式取液器的工作状态仿真既包含液体与贮箱的耦合也包含液体与取液器的耦合,难以采用单一算法求解。结合一般耦合算法与ALE耦合算法,实现了对于柔性随动取液器的运动模拟仿真,分析了影响取液器随动性能的设计参数。结论表明,波纹管壁厚在1.5~2.5mm时取液器随动性较好,同时可减轻取液头质量有助于减少结构剩油。Flexible servo type liquid extractor is a new type of anti-overload device. Considering the fact of coupled working state between the liquid and the oil tank, and between the liquid and the extractor, it is a difficult problem to carry out the numerical simulation with one single method. The combination of a general coupling algorithm and the ALE algorithm is presented in this paper. The numerical simulation of actual movement of flexible servo is carried out and the design parameters were analyzed. The result shows that the device has a good performance with the thickness ranging from 1.5 to 2.5mm and the decreasing of the weight of the head can reduce the oil remains.
