Abstract Detachment waves have recently been identified as one of the main sources for self-oscillation and accompanying energy losses in belt drive systems under low-speed and otherwise steady operation. In light of this, herein we explore mitigation of detachment wave-induced instabilities via regular and irregular texturing of the belt contact surface. The results document that surface texturing reduces the magnitude of belt drive oscillations, with the reduction being significantly more pronounced in the driver case than in the driven case. While both regular and irregular surface topographies are useful in minimizing the vibrations, regular patterns result in a stronger effect. The aspect ratio of surface projections is found to be the most important parameter, while excessive texturing of the belt surface is shown to result in belts losing their tractive capabilities.

最大限度地减少皮带传动中的自振荡：表面纹理

摘要 分离波最近被确定为皮带传动系统在低速和其他稳定运行下自振荡和伴随能量损失的主要来源之一。鉴于此，我们在此探索通过带接触表面的规则和不规则纹理来减轻脱离波引起的不稳定性。结果表明，表面纹理减少了皮带驱动振动的幅度，驱动情况下的减少比从动情况下明显更明显。虽然规则和不规则的表面形貌都有助于最大限度地减少振动，但规则的图案会产生更强的效果。发现表面投影的纵横比是最重要的参数，
