Component design of rubber-based anti-vibration devices remains a challenge, since there is a lack of predictive models in the typical regimes encountered by anti-vibration devices that are deformed to medium dynamic strains (0.5 to 3.5) at medium strain rates (0.5/s to 10/s). An approach is proposed that demonstrates all non-linear viscoelastic effects such as hysteresis and cyclic stress softening. As it is based on a free-energy, it is fast and easily implementable. The fitting parameters behave meaningfully when changing the filler volume fraction. The model was implemented for use in the commercial finite element software ABAQUS. Examples of how to fit experimental data and simulations for a variety of carbon black filled natural rubber compounds are presented.
橡胶基减振装置的部件设计仍然是一个挑战，因为在减振装置所遇到的典型工况中缺乏预测模型，这些工况下减振装置在中等应变速率（0.5/s至10/s）下变形至中等动态应变（0.5至3.5）。本文提出了一种方法，该方法能体现所有非线性粘弹性效应，如滞后和循环应力软化。由于它基于自由能，所以速度快且易于实现。当改变填料体积分数时，拟合参数表现出有意义的变化。该模型已在商业有限元软件ABAQUS中实现。文中给出了如何对各种炭黑填充天然橡胶复合材料的实验数据进行拟合以及模拟的示例。
