Abstract An experimental study is conducted for friction systems introducing damping components consisting of different materials and different configuration. A number of experiments are performed on a pad-on-disc experimental test rig. Dynamic and tribological analyses are performed to evaluate the effects of different damping components on the stick–slip behavior. The obtained results indicate that friction systems introducing damping components of styrene butadiene rubber (SBR) or Mu-Cu damping alloy (DA) materials effectively reduce the friction-induced stick–slip behavior. The best performance was observed for the SBR damping component with a specific structure. The mechanism of introducing SBR or DA damping components into friction systems to influence the stick–slip behavior is discussed. For the SBR damping component, deformation is the dominant factor to suppress the stick–slip behavior. This is because the larger deformation of damping component could dissipate the vibration energy of friction systems and alleviate severe wear phenomena at the contact interface. For the DA damping components, the main reason for the reduction in stick–slip behavior is that the material has a higher damping capacity. Therefore, damping components of DA material only affect the vibration characteristics and not surface wear characteristics of the contact interface. The purpose of this article is to provide novel insights for the reduction or elimination of stick–slip motion at low speeds in relevant engineering applications.

通过引入阻尼材料抑制摩擦引起的粘滑行为并改善滑动系统的摩擦学特性

摘要 针对摩擦系统引入了不同材料和不同配置的阻尼元件进行了实验研究。许多实验是在盘式试验台上进行的。进行动态和摩擦学分析以评估不同阻尼组件对粘滑行为的影响。获得的结果表明,摩擦系统引入了丁苯橡胶 (SBR) 或 Mu-Cu 阻尼合金 (DA) 材料的阻尼组件,有效地减少了摩擦引起的粘滑行为。观察到具有特定结构的 SBR 阻尼组件的最佳性能。讨论了将 SBR 或 DA 阻尼组件引入摩擦系统以影响粘滑行为的机制。对于 SBR 阻尼组件,变形是抑制粘滑行为的主要因素。这是因为阻尼元件较大的变形可以消散摩擦系统的振动能量,减轻接触界面处的严重磨损现象。对于 DA 阻尼组件,粘滑行为降低的主要原因是材料具有更高的阻尼能力。因此,DA材料的阻尼成分只影响振动特性,而不影响接触界面的表面磨损特性。本文的目的是为减少或消除相关工程应用中的低速粘滑运动提供新的见解。这是因为阻尼元件较大的变形可以消散摩擦系统的振动能量,减轻接触界面处的严重磨损现象。对于 DA 阻尼组件,粘滑行为降低的主要原因是材料具有更高的阻尼能力。因此,DA材料的阻尼成分只影响振动特性,而不影响接触界面的表面磨损特性。本文的目的是为在相关工程应用中减少或消除低速下的粘滑运动提供新的见解。这是因为阻尼元件较大的变形可以消散摩擦系统的振动能量,减轻接触界面处的严重磨损现象。对于 DA 阻尼组件,粘滑行为降低的主要原因是材料具有更高的阻尼能力。因此,DA材料的阻尼成分只影响振动特性,而不影响接触界面的表面磨损特性。本文的目的是为在相关工程应用中减少或消除低速下的粘滑运动提供新的见解。DA 材料的阻尼元件只影响振动特性,而不影响接触界面的表面磨损特性。本文的目的是为在相关工程应用中减少或消除低速下的粘滑运动提供新的见解。DA 材料的阻尼元件只影响振动特性,而不影响接触界面的表面磨损特性。本文的目的是为在相关工程应用中减少或消除低速下的粘滑运动提供新的见解。
