Abstract

Taking damping into account in the problems of structural dynamics is an important and nontrivial problem. Its complexity is primarily determined by the required specification of correct characteristics of the materials used and the choice of a model suitable for analysis. We consider some models of viscoelastic materials as regards the possibility of applying these models in harmonic analysis of damping properties of various materials in the linear range of elastic strains. The proposed analysis is based on the use of parameters of viscoelastic materials, which are specified as coefficients of a differential equation of small forced vibrations. It is shown that the models considered here are characterized by different frequency dependences of parameters of materials being simulated. This makes it possible to combine a model with frequency dependences of its parameters close to the frequency characteristics of parameters of viscoelastic materials under investigation.

由粘弹性材料制成的阻尼器的模拟

摘要

在结构动力学问题中考虑阻尼是一个重要且重要的问题。它的复杂性主要取决于所用材料的正确特性的所需规格以及适合分析的模型的选择。我们考虑将粘弹性材料的某些模型应用于在弹性应变线性范围内对各种材料的阻尼特性进行谐波分析的可能性。所提出的分析基于使用粘弹性材料的参数，这些参数被指定为小的强迫振动的微分方程的系数。结果表明，此处考虑的模型的特征在于所模拟材料的参数具有不同的频率依赖性。
