摘　　要：为满足ARJ21-700飞机模拟冰型试飞试验的需要,设计了一种新型复合材料夹层结构模拟冰型,对其用材、加工方式、安装方法进行了选定。选取模拟冰型典型段,制作试验件,通过地面模拟试验,得出了模拟冰型的脱落破坏载荷。基于界面元法,在ABAQUS中使用内聚力单元模拟胶接界面,计算出模拟冰型的脱落破坏载荷,计算结果与试验结果吻合良好,说明了数值模拟方法的准确性。试验、计算得出的破坏载荷都高于冰型实际受载,证明了本文设计方案可行,该种复合材料夹层结构模拟冰型可用于ARJ21-700飞机的试飞试验。To meet the flight test need of simulated ice shape tor ARJ21-700, a new kind of composite sandwich simulated ice shape is designed. The material choosing, processing methods and installation methods are determined. A typical block of simulated ice shape is manufactured and tested to obtain its debonding load. Numerical analysis of the debonding load is carried out by ABAQUS software in which cohesive elements are employed. Good agreement between experimental results and numerical results proves the valid of the interface element method. The debonding loads from both the experiment and simulation are higher than the actual load. It can be concluded that the ice shape design in this paper is feasible. This kind of composite sandwich simulated ice shape can be used for the flight test of ARJ21- 700.
