摘要

目的工业传动系统使用湿式盘式离合器实现安全可靠的换档。过去几十年来，润滑剂配方和摩擦材料成分方面的进步为可靠的离合器系统提供了保障。在这种情况下，摩擦性能对于离合器的正确操作至关重要。然而，摩擦行为及其影响因素仍是现代研究的对象。本研究的目的是调查钢盘的选择如何影响湿式工业离合器的噪音、振动和颠簸（NVH）性能。为了调查钢盘对工业湿式盘式离合器的摩擦和 NVH 性能的影响，对相关摩擦系统进行了实验调查。这些试验是在两个优化的试验台架上进行的，保证了试验结果的可移植性。对一种摩擦系统的钢盘和摩擦衬里的表面形貌进行了测量，以确定表面形貌和摩擦行为之间可能存在的关系。使用不同的钢盘表面光洁度，相应的结果会显示出不同的抖动趋势，从而导致不利的 NVH 行为--摩擦系数随滑动速度的不同梯度导致了这种现象的产生。它为工程师优化现代摩擦系统提供了支持。同行评议本文的同行评议历史见：https://publons.com/publon/10.1108/ILT-02-2024-0054/。

Influence of the steel disk on the NVH behavior of industrial wet disk clutches

Purpose Industrial drivetrains use wet disk clutches for safe and reliable shifting. Advances over the past decades regarding the formulation of lubricants and the composition of friction materials have led to reliable clutch systems. In this context, the friction behavior is crucial for the correct operation of the clutch. Nevertheless, the friction behavior and its influencing factors are still the object of modern research. The purpose of this study is to investigate how the choice of the steel disk influences the noise vibration and harshness (NVH) behavior of wet industrial clutches. Design/methodology/approach To investigate the influence of the steel disk on the friction and NVH behavior of industrial wet disk clutches, experimental investigations with relevant friction systems are conducted. These tests are performed at two optimized test rigs, guaranteeing transferable insights. The surface topography of the steel disk and the friction lining are measured for one friction system to identify possible relations between the surface topography and the friction behavior. Findings The steel disk can influence the friction behavior of wet disk clutches. Using a different steel disk surface finish, corresponding results can show differences in the shudder tendency, leading to a nonfavorable NVH behavior – different gradients of the coefficient of friction over sliding velocity cause this phenomenon. Originality/value This work gives novel insights into the friction and NVH behavior of industrial wet disk clutches. It supports engineers in the optimization of modern friction systems.
