摘　　要：复合材料舷窗结构作为飞行器的重要组成部件,对其强度进行研究具有重要意义。采用试验与数值模拟相结合的方法对舷窗结构的力学行为进行研究,首先得到结构件的极限剪切载荷,然后建立基于连续介质损伤力学(CDM)的数值模型进行仿真模拟。结果表明:所建立的数值模型可以准确预测结构件的强度值及损伤破坏部位。Composite window frame structure is an important component of the aircraft .It is of significant im-portance to study the strength .The experimental research method combine with the numerical simulation are used to study the mechanical behavior of this structure .The ultimate shear load of the structure is got at first . Then ,a numerical simulation model based on the continuum damage mechanics（CDM ） is built .The numerical simulation results show that this model can accurately predict the intensity values and the destruction of dam-aged structure .
