The majority of mechanical systems which require damping exhibit more than one direction of motion. As the state of the art shows, there is no machine element which can provide independently adjustable damping in more than one direction of motion. The technical opportunities delivered by electro- and magnetorheological fluids shall be utilised to create a semi-active adjustable, multidimensional damper element, which is able to provide targeted damping forces in more than one direction of motion. Therefore mechanisms that have proven to be suitable for conventional unidirectional dampers provide the basis to develop fluid-mechanical concepts that can provide independent dissipation in more than one direction of motion. The most promising of these elaborated concepts will be worked out in detail by appropriate models, constructed and implemented in an exemplary vibration system. Through model based analysis and experiments the functional capabilities of the new multi-DOF damper will be demonstrated. By means of novel mechanisms that offer independent adjustability of dissipation in several directions of motion, integrated into one self-contained machine element, it will be possible to exert more aimed influence in vibration damping. Incorporating the functionality of multiple single-DOF dampers into one compact machine element additionally leads to a reduction of weight and costs. The complex and time consuming design task of installing several single-DOF dampers at a suitable position can be simplified to placing only one multi-DOF damper.

大多数需要阻尼的机械系统表现出不止一个运动方向。如现有技术所示，不存在能够在多于一个运动方向上提供独立可调阻尼的机器元件。应利用电流变和磁流变流体提供的技术机会来创建半主动可调节的多维阻尼器元件，其能够在多个运动方向上提供目标阻尼力。因此，已被证明适用于常规单向阻尼器的机构为开发流体机械概念提供了基础，该流体机械概念可以在多于一个运动方向上提供独立耗散。最有前途的这些详细的概念将制定出详细的适当的模型，构建和实施的一个示例性的振动系统。通过基于模型的分析和实验，新的多自由度阻尼器的功能能力将被证明。通过在几个运动方向上提供独立的耗散可调性的新颖机构，集成到一个独立的机器元件中，将有可能在振动阻尼方面发挥更有针对性的影响。将多个单自由度阻尼器的功能扩展到一个紧凑的机器元件中还导致重量和成本的降低。在合适的位置安装多个单自由度阻尼器的复杂和耗时的设计任务可以简化为仅放置一个多自由度阻尼器。
