Development of a methodology for the derivation of variations in PGE on the basis of partially quantified embodiment-function-models using the example of clutch judder by forced excitation

该研究项目的主要目标是回答这样一个问题，即如何在开发新一代产品（PGE -产品生成工程）时系统地导出子系统的变化，该问题基于部分量化的功能模型，该模型基于C&C2方法。将开发由此产生的方法，并首先使用强制激励引起的离合器抖动示例进行评估，并将记录在指南中。第一个子目标是生成用作示例的技术系统的合适的功能模型。除了模型本身之外，关于建模过程的进一步见解将从该活动中产生，例如关于可以做出的适当的细节和简化假设的级别。对于变分的推导，不仅要定性地而且要定量地了解函数关系。然而，由于所需的努力，不可能量化整个系统的这些关系。因此，假设是必要的，规定哪些数据是相关的定量描述，他们必须在系统中收集，最终能够得出所需的变化。用于此目的的方法将是预期指南的重要组成部分。收集所需的数据需要建立一个合适的测试环境。将收集到的数据和定性模型结合起来，可以得到一个部分量化的模型，作为下一步的基础。最后，研究了利用这些模型推导各子系统变化量的方法，目的是通过变化量来减小强迫激励引起的离合器抖动。从生成的变体的总集合中，选择最有希望的变体并在物理上实现（开发代），并使用构建的测试环境进行测试。发展世代、基本思想和新收集的数据是研究项目的重要成果。在此基础上，inteded指南还将包括用于解释收集数据的见解和方法，变异的推导以及基于其估计潜力和风险选择开发世代。

The main objective of the research project is answering the question how variations of subsystems can be derived systematically in the development of a new product generation (PGE - Product Generation Engineering), based on partially quantified embodiment-function-models which are based on the C&C2 approach. The resulting methodology will be developed and firstly evaluated using the example of clutch judder by forced excitation and will be documented in a guideline. The first subgoal is the generation of a suitable embodiment-function-model of the technical system which is used as an example. Apart from the model itself further insights regarding the modeling process will result from this activity, for example about the appropriate level of detail and simplifying assumptions that can be made. For the derivation of variations it is necessary to know the embodiment-function-relations not only qualitatively but also quantitatively. However a quantification of those relations for the complete system is not possible due to the required effort. Hence, hypotheses are necessary specifying which data are relevant for a quantitative description and where they have to be collected in the system to be finally able to derive the desired variations. A method for this purpose will be a substantial part of the intended guideline. Collecting the wanted data requires the set up of a suitable testing environment. Combining the gathered data and the qualitative model gives a partially quantified model as a basis for the next steps. Conclusively the method to derive variations of subsystems using those models is investigated, aiming at variations to reduce the clutch judder by forced excitation. From the total set of generated variations the most promissing are selected and implemented physically (development generations) and tested using the built testing environment. The development generations, the underlying ideas and the new gathered date are important results of the research project. Based on them the inteded guideline will also include insights and methods for the interpretation of gathered date, the derivation of variations and the selection of development generations based on their estimated potential and risk.
