摘要
高压玻璃钢管道以其优异的性能被广泛应用于石油储运领域,如何提高玻璃钢管道的耐压能力成为目前研究的热点。本文从树脂的黏度特性角度出发,将提高管道耐压能力的问题转化成对管道成型工艺过程中的温度控制问题。利用有限元软件ANSYS和APDL语言开发了数值模拟程序,对采用传统恒温加热的固化成型工艺的缠绕过程进行了数值模拟,分析了外表面温度变化规律,并通过优化缠绕过程的加温历程使复合材料外表面温度在期望的范围内。
With outstanding performance, the high pressure GRP pipes are widely used in the petroleum storage and transportation. How to improve the pressure-proof capability of GRP pipe is a research hotspot at present. Based on the property of resin viscosity, the goal to improve the pressure-proof capability becomes the problem of temperature control during the process of pipe forming. The numerical simulation program of the composite curing process is developed by ANSYS based on APDL. The winding process of curing method by constant temperature heating is simulated, and the change law of the temperature on the outer surface is obtained through analysis. Finally, the heating course is optimized, which keeps the temperature of outer surface in desired range.
