Planar Miniaturized Rotational Drive - PlateDrive

这个项目的总体目标是实现一种基于微结构碳纤维摩擦层和结构集成的压电致动弯曲元件的微型旋转执行器。通过结构弯曲元件和压电层的集成，被动金属片将变成主动定子，以实现弯曲元件的振动。定子和转子之间的微结构碳纤维摩擦层产生旋转的力和机械能量传递。该项目计划在Darmstadt理工学院EMK研究所(Schlaak教授)和FG Dünne Schichten(Alff教授)之间进行密切合作。两位合作者各自的研究领域被定义为：施拉克教授的研究领域，EMK研究所的立场：摩擦层的生产和研究。Schlaak教授的团队的目标包括在Alff教授的团队中制备用于生长压电层的弯曲元件，以及研究摩擦层的技术可行性、可重复性生产及其计量特性。Allf教授的目标包括实现有源弯曲元件(由Schlaak教授提供的生长在金属衬底上的压电层)以及为其弯曲行为建立模拟模型的概念，以表征和改进层状结构。主要目标仍然是在定子上生产功能集成的主动弯曲元件，并改善电气和机械性能。除了两个合作伙伴的目标的依赖性之外，还计划在项目开始时为规范的定义和随后的中间目标的执行进行密切合作。此外，将所有部件集成到演示设备中也将由两个合作者完成，并对其进行表征，为其计划测量设备。在PlateDrive演示设备的生产调查中，三层结构在机械上尽可能简单将是非常重要的。为此，执行器的第一个演示将主要基于大规模的制造方法。由于结构集成，小型化旋转致动器PlateDrive计划分几个步骤制造。因此，这种执行器在未来的大规模生产中将具有很高的性价比。

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.
