Abstract

The temperature dependences and the relationship between the indices of internal and external friction of carbon steel under the influence of thermal treatment were studied. It is shown that dissipative properties of friction contact are determined by thermally activated processes of relaxation and hysteresis internal friction, which cause stress relaxation and can be accompanied by both softening and strengthening of steel during contact interaction. Rheological influence models on the dynamic strain of the friction contact of its viscoelastic properties were observed. It is shown that the relationship between deformation and adhesive component parts of external friction force depends on two rheological characteristics that are responsible for dissipative properties: the dynamic modulus of elasticity under shear and the internal friction level.

钢摩擦过程中松弛过程与耗散过程之间的联系

摘要

研究了热处理条件下碳钢的温度依赖性及其内外摩擦指数之间的关系。结果表明，摩擦接触的耗散特性是由热激活的松弛和磁滞内摩擦过程决定的，这些过程会引起应力松弛，并且在接触相互作用过程中会伴随着钢的软化和强化。观察到流变模型对摩擦接触的动态应变及其粘弹性的影响。结果表明，变形与外摩擦力的粘合剂组成部分之间的关​​系取决于两个决定耗散性能的流变特性：剪切时的动态弹性模量和内摩擦水平。
