Field-Responsive Fluid Based Multi-Degree-of-Freedom Dampers for Independently Adjustable Dissipation - Second Period

大多数需要阻尼的机械系统表现出不止一个运动方向。正如目前的技术状况所示，没有一种机器元件可以在多个运动方向上提供独立可调的阻尼。利用电磁流变流体提供的技术机会，可以制造半主动可调的多维阻尼元件，能够在多个运动方向上提供目标阻尼力。因此，已被证明适用于传统单向阻尼器的机构为发展能够在多个运动方向上提供独立耗散的流体力学概念提供了基础。在这些详细阐述的概念中，最有希望的将通过适当的模型来详细阐述，并在一个示例性振动系统中构建和实现。通过模型分析和实验验证了新型多自由度阻尼器的性能。通过在多个运动方向上提供独立可调耗散的新型机构，集成到一个独立的机械元件中，将有可能在减振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整合到一个紧凑的机器元件中，还可以减少重量和成本。在合适的位置安装多个单自由度阻尼器的复杂而耗时的设计任务可以简化为只放置一个多自由度阻尼器。

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.
