This contribution deals with the development of a new shear specimen, which allows precise simple shear measurements for large shear values. The main idea is that the shear load for the rubber mat is applied via steel pins. A form fit connection has the advantage that for the load application, no clamping force or high friction coefficient is required. In addition, the disadvantages resulting from vulcanisation or bonding, for example, shrinkage, are avoided. This offers the big advantage that homogeneous ageing tests can be performed, and also fibre‐reinforced materials can be tested. In order to show the potential of the new pin design, simulation results are compared to each other, and also a first experimental implementation is conducted. The new shear specimen can be used for phenomenological investigations of rubber properties, like Payne effect, Mullins effect, anisotropy, permanent set, softening, recovery, creep and relaxation behaviour.

开发用于精确简单地测量橡胶垫的剪切装置

这一贡献与新剪切样本的开发有关，该样本可以对大剪切值进行精确的简单剪切测量。主要思想是，橡胶垫的剪切载荷是通过钢钉施加的。形状配合连接的优点在于，对于负载应用，不需要夹紧力或高摩擦系数。另外，避免了由硫化或粘结引起的缺点，例如收缩。这具有很大的优势，可以执行均质的老化测试，还可以测试纤维增强材料。为了展示新引脚设计的潜力，将仿真结果相互比较，并进行了第一个实验实现。新的剪切试样可用于橡胶特性的现象学研究，
