As an energy carrier, green hydrogen will play a central role in the decarbonization of high-emission sectors. There are potential synergy effects for the technologies required that have not yet been sufficiently researched and utilized. Using the...

The thermal runaway of batteries is a key safety issue, as the cells can catch fire and explode due to uncontrolled heating. In addition to conventional lithium-ion batteries, the industry is focusing on sodium-ion batteries, the safety behavior of...

The assessment of battery condition, from the overall system to the cell level, remains a challenge, particularly outside the laboratory environment. The aging mechanisms occurring within the cell are intricately superimposed, making a clear...

Hairpin technology has established itself as the standard for electric drives due to the possibility of substituting stochastic winding and drawing-in processes with deterministic forming and assembly processes. At the same time, the technology is...

As a mechanical transmission element, the ball screw is well-established for generating feed motion in machine tools (MT) and has replaced hydraulic power steering in motor vehicles (MV). While interval controlled central lubrication in MTs often...

This study investigates the feasibility of various classification algorithms for real-time, machine-independent instability detection in milling processes. Based on 136 measurements with 5.6 million data points, two new classification methods are...

As a key component of a milling machine, the main spindle decisively determines the accuracy and performance limits of the milling process. During machining, the spindle is simultaneously subjected to static and dynamic loads. Variations in process...

The validation of product characteristics is a key success factor in the development of increasingly software-driven systems. An incomplete requirements elicitation is one of the main causes of development errors and product recalls. An integrated...

This approach for role allocation in Model-based Systems Engineering (MBSE) differentiates between process-oriented and model-oriented roles to enhance efficiency and interoperability in MBSE. By integrating existing competency frameworks and best...

Modern machine tools are equipped with numerous sensors that can be used for process monitoring. However, the underlying models exhibit residual uncertainties, for example due to friction, which can lead to inaccurate results. Data-driven approaches...

This article presents a mobile assistance system for communication and interaction in heterogeneous assembly tasks in SMEs. The assistance system was iteratively developed as a prototype tablet app with the involvement of assembly workers from two...

Collaborative robotics tries to combine the strengths of humans and robots. This article discusses incorporating object detection into a behavior tree (BT), a common hierarchical control structure in robotics. This integration allows robots to...
