摘要: 应用ANSYS参数化设计语言(APDL)开发复合材料层合板机械连接结构的ANSYS分析模块,实现有限元分析前处理过程的参数化建模和后处理过程的累积损伤可视化仿真。建立三维累积损伤有限元模型,采用ANSYS中柔体对柔体的面—面接触单元对螺栓表面和复合材料层合板孔壁间的接触行为进行模拟。进行的T300帘子布/QY8911双马来酰亚胺树脂层合板单钉单搭螺栓挤压强度试验验证此分析模块的有效性,对不同几何参数、不同铺层类型的复合材料层合板机械连接结构的承载性能进行可视化仿真模拟。

Abstract: A parameterized simulation program is developed to predict the response of composite laminates with single bolt structure. The three-dimensional non-linear progressive damage model is developed on the platform of ANSYS using APDL. Parameterized modeling and progressive damage simulation could be achieved in this analysis. The analysis takes into account the contact at bolt-hole interface. The effects of stacking sequences and geometrical parameters on the bearing strength are determined experimentally. For all the analyses performed, the damage progression of single bolted joint is predicted.

Key words: structure simulation, composite laminates, mechanically joints, progressive damage, contact model
