Particle dampers show a huge potential to reduce undesired vibrations in technical applications even under harsh environmental conditions. However, their energy dissipation depends on many effects on the micro- and macroscopic scale, which are not fully understood yet. This paper aims toward the development of design rules for particle dampers by looking at both scales. This shall shorten the design process for future applications. The energy dissipation and loss factor of different configurations are analyzed via the complex power for a large excitation range. Comparisons to discrete element simulations show a good qualitative agreement. These simulations give an insight into the process in the damper. For monodisperse systems, a direct correlation of the loss factor to the motion modes of the rheology behavior is shown. For well-known excitation conditions, simple design rules are derived. First investigations into polydisperse settings are made, showing a potential for a more robust damping behavior.

颗粒阻尼器显示出巨大的潜力，即使在恶劣的环境条件下，也可以减少技术应用中不希望的振动。但是，它们的能量耗散取决于微观和宏观尺度上的许多影响，目前还没有完全了解。本文着眼于两个尺度，旨在开发颗粒阻尼器的设计规则。这将缩短未来应用程序的设计过程。在大激励范围内，通过复数功率分析了不同配置的能量耗散和损耗因子。与离散元素模拟的比较显示出良好的定性一致性。这些模拟可以深入了解风门的过程。对于单分散体系，显示了损耗因子与流变行为的运动模式的直接相关性。对于众所周知的激励条件，可以得出简单的设计规则。首先对多分散性设置进行了研究，显示出更健壮的阻尼行为的潜力。
