螺栓联接是最常用的机械零件之一。将各种大小的结构结合在一起，完整性就落在了他们的肩上。因此，准确可靠的接头装配是至关重要的。虽然它的目标是完全不经历摩擦引起的振动，但在某些情况下，它是不可避免的。然而，由于过程的易变性，这些情况还没有超出控制算法的重点。这一贡献提供了关于螺栓连接紧固过程中摩擦诱发振动发生的分析和实验结果。可以验证以前的系统特征常数的结果，即使在紧固过程中发生强烈振动时，也可以用它来监测紧固过程。此外，还提出了一种实时算法，它通过识别过程特性来实现高级过程监视和控制，基于这些特性可以对过程进行预测。这些措施大大提高了达到紧缩进程目标值的能力。
Bolted joints are one of the most used machine elements. Holding together structures of all sizes, the integrity rests on their shoulders. Thus, an accurate and reliable assembly of the joint is crucial. While it is the aim to not experience friction-induced vibrations at all, at some situations, it is unavoidable. These cases, however, have yet been out of the focus of control algorithms due to the volatile nature of the process. This contribution delivers analytical and experimental results for the occurrence of friction-induced vibrations during tightening of bolted joints. Previous findings of system characteristic constants could be validated, which can be used to monitor the tightening process even while strong vibrations during the tightening process occur. Additionally, a real-time algorithm is presented which allows for an advanced process monitoring and control by identifying process characteristics based on which predictions of the process can be made. These measures significantly improve the capabilities to reach the target values of the tightening process.
