Design of pipediameter of tubular textile composite for pipeline rehabilitation

  • 摘要: 系统地介绍了管状纺织复合材料管径设计原理,提出了管状纺织复合材料的弹性与热缩性能是影响管径设计的关键因素。采用有限元方法分析了管状纺织复合材料翻衬时的环向应变。结果表明,应根据管状纺织复合材料弹性的大小, 调节管径设计值。采用SPSS 软件对管状纺织复合材料的热缩性能进行分析,建立了反映热缩时间、热缩温度与缩率之间关系的数学模型。
    Abstract: In order to avoid the creases and ret ractation of the tubular textile composite in the pipeline because of design irrationality of pipediameter of tubular textile composite, the principle of the design was int roduced, and the elasticity and hot shrinkage property of the tubular textile composite as the key factors were proposed. The strain in the circular direction was analyzed by the finite element when the tubular textile composite was inversed. The results show that the design data of the pipediameter should be adjusted depending on the elasticity of the tubular textile composite. The hot shrinkage property was analysed by the software of SPSS and a model related with hot shrinkage, temperature and time was established.
