Synthesis of compliant mechanisms in force measurement and weighing technology for precision applications

该项目的目标是开发和实验验证基于模型的综合方法和综合准则的顺应机构在力测量和称重技术。第一次，将建立一个基于对物理效应（如弹性后效和温度依赖性）的基础研究的分析模型。基于对现有技术的分析，变得清楚的是，虽然存在用于柔顺机构的合成方法，但是根据当前的知识状态，这不适用于力测量和称重技术中的基于应变计的变形体。在这一领域的具体系统有特定的要求，柔顺机构的设计，所以有一个特别需要开发新的综合方法。拟议的项目旨在为缩小研究方面的这一差距作出重大贡献。具体的机制是要检查计量，以检查是否可以减少所需的因素10的帮助下，开发的模型和方法的力测量的不确定性。由于机械制造的质量对单个柔性铰链和整个柔性机构的运动特性具有相当大的影响，因此应进行测量以量化制造公差对机构的影响。这将以稳健性和敏感性分析的形式提供。在已开发的分析模型进行了计量学验证，综合方法的开发。因此，将发现用于设计柔性机构作为力传感器的新颖解决方案，例如，以大幅降低所使用的几何形状的复杂性。最后，在已开发的合成方法或工具的基础上，将设计出能够并支持在未来应用中将柔顺机构解释为力传感器的方法或工具。

The goal of the project is the development and experimental validation of model-based synthesis methods and synthesis guidelines for compliant mechanisms in force measurement and weighing technology. For the first time, an analytical model based on fundamental research into physical effects, such as elastic after-effects and temperature dependencies, will be build up. Based on the analysis of the state of the art, it becomes clear that although synthesis approaches for compliant mechanisms exist, according to the current state of knowledge, this does not apply to strain gauge based deformation bodies in force measurement and weighing technology. Concrete systems in this field have specific requirements for the design of the compliant mechanisms, so there is a particular need to develop novel synthesis methods. The proposed project is intended to make a significant contribution to closing this gap in research. The specific mechanisms are to be examined metrologically in order to examine whether the uncertainties of the force measurements can be reduced by the desired factor 10 with the help of the developed models and approaches. Since the quality of the mechanical manufacturing has a considerable influence on the movement properties of individual flexure hinges and entire compliant mechanisms, measurements should be carried out to quantify the effects of the manufacturing tolerances on the mechanisms. This will be provided in the form of a robustness and sensitivity analysis. After the developed analytical model has been metrologically verified, synthesis methods are developed. Thus, novel solutions for the design of compliant mechanisms as force sensors are to be found, for example, to drastically reduce the complexity of the geometries used. Finally, on the basis of the developed synthesis methods or tools are to be designed which enable and support the interpretation of the compliant mechanisms as force sensors in future applications.
