摘要

传感机器元件提供了升级传统机器元件的潜力,通过扩展其主要功能,能够在技术系统的原点测量感兴趣的数量,即所谓的原位测量。为了确保这些下一代机器元件的功能,必须特别注意建模方面的不确定性,以便能够正确评估所提供的信号并获得可靠的信息。因此,本贡献描述了一种基于可用信息量对传感技术中的不确定性进行分类的方法,特别是在中小企业中,这可以作为一个出发点,以减少发生的不确定性的影响,以提高获得的信号的鲁棒性。从不确定度的概念、分类方案及其与稳健设计的联系出发,提出了一个定量模型来确定不确定度对测量信号的影响。通过考虑到中小企业本身以及周围技术系统的不确定性,以传感同步带为例证明了所提出方法的适用性。

An approach for the quantitative description of uncertainty to support robust design in sensing technology
Abstract Sensing machine elements offer the potential to upgrade conventional machine elements by extending their primary function to be able to measure a quantity of interest at its point of origin in a technical system, the so-called in situ measurement. To ensure the functionality of these next generation machine elements, special attention must be paid to uncertainty in terms of modelling to be able to correctly evaluate the provided signal and obtain reliable information. Consequently, this contribution describes an approach to classify uncertainty in sensing technology, especially in SMEs, based on the amount of available information, which can be used as a point of departure to reduce the impact of occurring uncertainty to improve the robustness of the obtained signal. Starting from the understanding of uncertainty and the corresponding classification scheme as well as its linkage to robust design from the Collaborative Research Centre 805, a quantitative model is presented to determine the impact of uncertainty on a measuring signal. The applicability of the proposed approach is demonstrated using the example of a sensing timing belt by taking into account the uncertainty from the SME itself and also from the surrounding technical system.
