摘要

复合材料具有比强度高和比刚度高的优点,应用于直升机传动系统尾传动轴可有效减轻结构重量。复合材料传动轴与法兰一般采用铆钉连接,铆接区域是尾传动轴的薄弱环节。利用Ansys ACP软件建立复合材料尾传动轴与法兰的铆接分析模型,铆接区域的失效判据采用Tsai-Wu失效准则。当铆接位置的失效区域超出垫片覆盖区域,认为铆接结构失去承载能力。通过与尾传动轴静扭试验结果对比,本文的计算结果与试验结果吻合的很好。

Abstract

The composite material has the advantages of high specific strength and high specific stiffness, which could reduce the structural weight effectively when it was applied to the tail shaft of helicopter transmission system. The connection with the composite tail shaft and flange usually adopt riveting, the riveted area was the weakness of the tail shaft. In this paper, the riveting analysis model of composite tail shaft and flange was established by ANSYS ACP software. The Tsai-Wu failure criterion was adopted for the failure of the riveted joints. The riveting structure lost its function of carrying capacity when the failure zone of the riveting was more than the coverage area of gasket. By comparing with the results of static torsion test, the calculated results were in good agreement with the experimental results.
