The general aim of this project is the realization of a miniaturized rotating actuator based on a micro-structured frictional layer of carbon fibers and structurally integrated piezoelectric actuated bending elements.A passive metal sheet will be turned into an active stator through integration of structured bending elements and piezoelectric layers to achieve oscillation of the bending elements.The micro-structured frictional layer of carbon fibers between the stator and rotor generates the force and mechanical energy transfer for the rotation of the rotor.A close collaboration between the Institute EMK (Prof. Schlaak) and FG Dünne Schichten (Prof. Alff), both at Technische Universität Darmstadt, is planned in the project. The respective research fields of both collaborators are defined as follows: Research field of the position by Prof. Schlaak, Institut EMK: Production and investigation of the frictional layer. The goals of Prof. Schlaak`s group comprise the preparation of bending elements, for the growth of piezoelectric layers at Prof. Alff`s group, as well as the research for the technical feasibility and reproducible production of the friction layer and its metrological characterization.Research field of Prof. Alff, FG Dünne Schichten: Growth and characterization of the structurally integrated piezoelectric layers. Prof. Allf`s goals include the realization of active bending elements (piezoelectric layers grown on metallic substrates provided by Prof. Schlaak) and the conception of a simulation model for their bending behavior to characterize and improve the layered structures. The main goal remains the production of functionally integrated active bending elements on the stator, with improved electrical and mechanical properties.In addition to the dependencies of both collaborating partners` goals, a close cooperation for the definition of specifications at the beginning of the project and for subsequent execution of the intermediate goals is also planned. Furthermore, the integration of all components into a demonstrator device will also be done by both collaborators as well as its characterization for which a measurement device is planned.In the investigations for the production of the PlateDrive demonstrator it will be of great importance that the three-layer arrangement is mechanically as simple as possible. For this reason, the first demonstrator of the actuator will be mainly based on large-scale manufacturing methods. The miniaturized rotational actuator PlateDrive is planned to be manufactured in a few steps due to the structural integration. Therefore, this actuator will be highly cost-effective for large-scale production in the future.

本项目的总体目标是实现一种基于碳纤维微结构摩擦层和结构集成压电驱动弯曲元件的小型化旋转驱动器。通过结构弯曲元件和压电层的集成，将被动金属片变成主动定子，实现弯曲元件的振动。微驱动器的结构简单，成本低。定子和转子之间的碳纤维结构摩擦层产生的力和机械能传递的转子的旋转。研究所EMK之间的密切合作该项目计划邀请达姆施塔特工业大学的F.D. Schlaak教授和FG Dünne Schichten教授。双方合作者各自的研究领域如下：EMK研究所Schlaak教授的研究领域：摩擦层的生产和研究。Schlaak教授团队的目标包括为Alff教授团队的压电层生长制备弯曲元件，以及研究摩擦层的技术可行性和可重复生产及其性能表征。Alff教授，FG Dünne Schichten的研究领域：结构集成压电层的生长和表征。Allf教授的目标包括实现主动弯曲元件（Schlaak教授提供的在金属基板上生长的压电层）以及其弯曲行为的模拟模型的概念，以表征和改进分层结构。主要目标仍然是在定子上生产功能集成的主动弯曲元件，并提高电气和机械性能。除了合作伙伴的目标依赖性之外，还计划在项目开始时为规范定义以及随后的中期目标执行进行密切合作。此外，将所有组件集成到演示设备中也将由双方合作者完成，并对其进行表征，其中计划使用测量设备。在PlateDrive演示设备的生产研究中，三层布置在机械上尽可能简单非常重要。出于这个原因，致动器的第一个演示器将主要基于大规模制造方法。由于结构一体化，小型化旋转致动器PlateDrive计划在几个步骤中制造。因此，该致动器将具有很高的成本效益，用于未来的大规模生产。
