起重臂是起重机上三大结构件之一，是起重机中最重要的受力支撑件。为了解决起重机在户外工作过程中，面临不同风力下起重臂的受力情况，采用流固耦合方法计算分析。根据流体计算软件，实现了起重臂在流体域中建模与分析方法，计算了不同风级对起重臂的影响，得到了起重臂在背面迎风情况下受力最大的分析结果。

Gib arm, one of the 3 major structural parts, is the most important force of supporting. As for the stress state placed onto the gib arm under different wind-force in the fieldwork. The fluid-structure interaction is adopted in the analysis and calculation. According to CFD, in implements the modeling and analysis in the fluid domain and calculates the effects from different wind scale to the gib arm. it comes to a conclusion that the maximum force onto the gib arm while being against the wind from the back.
