Elastomeric layers, that serve as the base of a viscoelastic (VE) damping system in structures, dissipate energy through shear deformation and transform vibration energy into heat by internal friction between polymer chains. In this study, two compounds, based on natural rubber (NR) matrix and butyl rubber (IIR) matrix, were designed and manufactured. Then, the mechanical and dynamic properties of elastomeric layers were investigated. Dynamic loading tests were conducted on the elastomeric layers using a frequency range of 0.1–1.5 Hz and a shear strain range of 10–150% under harmonic loading in order to analyze their hysteretic behavior. The output of the experiments shows that the both of elastomeric layers have a large deformation capability with a high damping performance, but the IIR damper can provide high energy dissipation capacity compared with the NR damper that has a large restoring force. The results also show an increase in storage modulus and loss factor of VE dampers with increasing frequency and their decrease with increasing strain. However, the dependency of VE damper on strain and strain rate based on NR is more remarkable than that of VE damper based on IIR. The experimental data were also used for validation and calibration of numerical simulation by ABAQUS software. The results proved to be satisfactory.

弹性体层是结构中粘弹性（VE）阻尼系统的基础，它通过剪切变形来耗散能量，并通过聚合物链之间的内部摩擦将振动能转化为热量。在这项研究中，设计和制造了两种基于天然橡胶（NR）基质和丁基橡胶（IIR）基质的化合物。然后，研究了弹性体层的力学和动态性能。为了分析弹性体层的滞回性能，在谐波负荷下使用0.1–1.5 Hz的频率范围和10–150％的剪切应变范围对弹性体层进行了动态载荷测试。实验结果表明，两个弹性体层均具有较大的变形能力和较高的阻尼性能，但是，IIR阻尼器与具有较大恢复力的NR阻尼器相比，具有较高的能量消散能力。结果还表明，VE阻尼器的储能模量和损耗因子随频率增加而增加，随应变增加而减小。然而，VE阻尼器对基于NR的应变和应变率的依赖性比基于IIR的VE阻尼器更为显着。实验数据还用于通过ABAQUS软件进行数值模拟的验证和校准。结果证明是令人满意的。与基于IIR的VE阻尼器相比，基于NR的VE阻尼器对应变和应变率的依赖性更为显着。实验数据还用于通过ABAQUS软件进行数值模拟的验证和校准。结果证明是令人满意的。与基于IIR的VE阻尼器相比，基于NR的VE阻尼器对应变和应变率的依赖性更为显着。实验数据还用于通过ABAQUS软件进行数值模拟的验证和校准。结果证明是令人满意的。
