In this paper, experimental and numerical investigations on cord–elastomer composites are presented. A finite-element model is introduced, which was developed within the framework of an industrial project. The model is able to simulate an elastomer matrix with inserted cords as load bearing elements and to predict the strains and stresses in cord and elastomer sections. The inelastic material behavior of the elastomer matrix and the yarns is described by corresponding material models suitable for large deformation processes. With the help of a specially developed demonstrator bellows, which is similar to an air spring, the simulation results are compared with experiments. For this purpose, the digital image correlation method is used to determine the deformations on the outer surface of the demonstrator bellows and to calculate the strains on and between the cords. The comparison of the results shows that the employed simulation method is very well suited to predict the strains in these cord–elastomer composites.

在本文中，对帘线-弹性体复合材料进行了实验和数值研究。介绍了在工业项目框架内开发的有限元模型。该模型能够模拟以插入的帘线为承载元件的弹性体基质，并预测帘线和弹性体截面中的应变和应力。弹性体基体和纱线的非弹性材料性能通过适用于大变形过程的相应材料模型来描述。借助专门开发的示威器风箱（类似于空气弹簧），将模拟结果与实验进行了比较。以此目的，数字图像相关方法用于确定演示器波纹管外表面的变形并计算绳索上和绳索之间的应变。结果的比较表明，采用的模拟方法非常适合预测这些帘线-弹性体复合材料中的应变。
