由于灌装阀接口的结构会对灌装的速度和精度产生影响，针对这个问题应用CFX-ANSYS对灌装头的斜T型管接头进行了双向流固耦合分析，得到了斜T型管接头在灌装过程中的应力、应变以及管内流体的流动特性的变化。分析结果对灌装系统中的斜T型管接头的优化设计及使用维护，有一定的指导作用。

The structure of filling valve joint can affect the filling speed and precision. CFX-ANSYS method was used for flow-structure interaction analysis for inclined T-tube joint of filling head, and the stress, strain and fluid flow characteristics of the tube in the filling process was obtained. The analysis results can be guidance for the optimization design and maintenance of inclined T-tube joint.
