【摘要】：根据复合材料固化成型原理,建立采用连续编织-缠绕-拉挤成型工艺生产的复合材料直管的传热模型以及固化动力学模型,利用有限元软件ANSYS和APDL语言开发复合材料直管固化过程数值模拟程序,以三维复合材料直管为模型进行固化数值模拟仿真,从而分析不同参数对采用连续编织-缠绕-拉挤成型工艺复合材料直管固化成型过程中的温度与固化度的影响。通过对复合材料直管模型进行固化数值模拟仿真分析可以得到工艺参数(如初始温度、加温历程、拉挤速度等参数)对固化过程的影响规律。对应用连续编织-缠绕-拉挤成型工艺生产的复合材料直管进行在线温度测试,测试结果表明数值模拟与实际生产工艺贴合,对实际生产有指导意义。
[Abstract]:According to the principle of composite curing forming, the heat transfer model and curing dynamics model of composite straight tube produced by continuous braiding, winding and pultrusion process are established. The software ANSYS and APDL are used to develop the numerical simulation program of the curing process of the composite straight pipe, and the solidification numerical simulation is carried out with the three-dimensional straight pipe as the model. The effect of different parameters on the temperature and curing degree of the straight tube of composite material by continuous braiding, winding and pullout process was analyzed. The numerical simulation of the curing process of the straight pipe model of composite material was carried out. Process parameters can be obtained by analyzing (. Such as initial temperature. The influence of heating process, pullout speed and other parameters on the curing process. The on-line temperature test of the composite tube produced by continuous braiding, winding and pultrusion process was carried out. The test results show that the numerical simulation fits with the actual production process and has guiding significance for practical production.
