Abstract

The damping composites from the materials with different elastic hysteresis properties have been studied at dynamic loads and temperatures of +23°C and –40°C. A sandwich shock absorber for a rail damping element that is 14 mm in thickness from fiber-reinforced rubber composite and thermoplastic elastomer, which combines the advantages of each material, has been developed. A procedure for the choice of elastic hysteresis characteristics of sandwich shock absorbers and a mathematical model of a wagon–track multiple-mass vibration system making it possible to evaluate the applicability and performance of such shock absorbers have been proposed.

用于铁路运输夹层减震器的具有不同弹性滞后特性的材料阻尼复合材料

摘要

在动态载荷和+ 23°C和–40°C温度下，已经研究了具有不同弹性滞后特性的材料制成的阻尼复合材料。已经开发出一种用于轨道阻尼元件的三明治式减震器，该减震器由纤维增强的橡胶复合材料和热塑性弹性体制成，厚度为14 mm，结合了每种材料的优点。提出了一种用于选择夹层减震器弹性滞后特性的程序以及旅行车多质量振动系统的数学模型，从而可以评估这种减震器的适用性和性能。
