项目摘要

The reduction of traffic emission could be achieved by the use of lightweight materials. As well combustion engines as electrical drive concepts benefits from this technology. Especially fiber reinforced plastic (FRP) is a promising material for this kind of application. However, this also requires that such components can be produced in large numbers. A promising production process is the so called resin transfer molding process (RTM).Within the RTM process chain, a large number of handling activities are necessary, especially at the beginning. Individual layers of a semi-finished product have to be assembled to produce a stack of layers for the further RTM process. For this purpose, the individual layers have to be taken out from a storage stack, which requires a series of separation processes. For an automated process, it is important that this separation process is carried out with a high degree of process reliability. Although there are plenty of systems witch separate the different layers with a mechanical principle, but then again they do not have a one hundred percent reliability and could not detect a fault and thereby would interfere with an automated process. Thus, a sensor system is required which not only permits a separation process but also can control the result. Such a measuring principle is the resulting negative pressure in a vacuum gripper itself which is well suited for the handling of textile materials. However the vacuum in the gripper depends not only from the number of layers but also from many other factors. In order to be able to use a vacuum gripper for the separation process a model is required which simulates the expected values so that they can be compared with the measured ones. For this model the components in the gripping process are modeled separately and then coupled. With this model separation processes will be tested witch validate the model itself. In addition, the results are used to formulate rules for how the suction surface of a gripper has to be designed depending on the textile.In summary, the planned investigations will help to get a better understanding of the interrelationships in the handling of textile materials with vacuum grippers

通过使用轻质材料可以减少交通排放。以及作为电气驱动器概念的燃烧引擎从这项技术中受益。特别是纤维增强塑料（FRP）是这种应用的有前途的材料。但是，这也要求可以大量生产此类组件。有希望的生产过程是所谓的树脂传输成型过程（RTM）。在RTM过程链中，需要大量的处理活动，尤其是在开始时。必须组装半分配产品的各个层以生成一堆层以进行进一步的RTM过程。为此，必须从存储堆栈中取出各个层，这需要一系列的分离过程。对于自动化过程，重要的是要以高度的过程可靠性进行这种分离过程。尽管有很多系统与机械原理分开不同的层，但话又没有100％的可靠性，无法检测到故障，因此会干扰自动化过程。因此，需要传感器系统，不仅允许分离过程，而且可以控制结果。这样的测量原理是真空抓地力本身的负压，它非常适合处理纺织品。但是，抓地力中的真空不仅取决于层数，而且取决于许多其他因素。为了能够使用真空抓地力进行分离过程，需要模型，以模拟预期值，以便可以将它们与测量值进行比较。对于此模型，将夹具过程中的组件分别建模，然后耦合。使用此模型分离过程将进行测试，巫婆验证模型本身。此外，结果用于制定规则，以根据纺织品设计抓手的吸力表面如何设计。总而言之，计划的调查将有助于更好地了解使用真空夹具处理纺织品中的相互关系
