Abstract

For in-line characterization of pultruded profiles, two alternative ANSYS based finite element modelling approaches using the same continuous model with lumped material properties for the cured composite are developed, compared and discussed. The first procedure is developed in ANSYS Mechanical environment and based on the mixed time integration scheme and nodal control volumes method. The second procedure is performed by using ANSYS CFX software with the cure reaction introduced as an additional variable. Validation of the developed algorithms is realized by the analysis of pultrusion process for the rod profile controlled in-line by new cure sensors measuring the temperature and electrical resistivity of the resin on the profile surface.For in-line characterization of pultruded profiles, two alternative ANSYS based finite element modelling approaches using the same continuous model with lumped material properties for the cured composite are developed, compared and discussed. The first procedure is developed in ANSYS Mechanical environment and based on the mixed time integration scheme and nodal control volumes method. The second procedure is performed by using ANSYS CFX software with the cure reaction introduced as an additional variable. Validation of the developed algorithms is realized by the analysis of pultrusion process for the rod profile controlled in-line by new cure sensors measuring the temperature and electrical resistivity of the resin on the profile surface.

拉挤型材的在线表征

对于拉挤型材的在线表征，开发了两种基于ANSYS的有限元建模方法，使用具有集总材料特性的相同连续模型对固化复合材料进行了比较和讨论。第一个程序是在ANSYS机械环境下，基于混合时间积分方案和节点控制体积法开发的。第二步采用ANSYS CFX软件进行，并引入固化反应作为附加变量。利用新型固化传感器测量型材表面树脂的温度和电阻率，对棒材型材的拉挤过程进行了分析，验证了所开发算法的有效性。对于拉挤型材的在线表征，开发了两种基于ANSYS的有限元建模方法，使用具有集总材料特性的相同连续模型对固化复合材料进行了比较和讨论。第一个程序是在ANSYS机械环境下，基于混合时间积分方案和节点控制体积法开发的。第二步采用ANSYS CFX软件进行，并引入固化反应作为附加变量。利用新型固化传感器测量型材表面树脂的温度和电阻率，对棒材型材的拉挤过程进行了分析，验证了所开发算法的有效性。
