Optimierung der Kernherstellung durch numerische Simulation
The core shooting process is based on the sudden expansion of a limited compressed air volume, which shoots the molding material into the core box with high velocity. Apart from the mould filling the purpose is to release an adequate compression of the molding material. During the entire time it is …

Shape Evolution of Nanostructures by Thermal and Ion Beam Processing
Single-crystalline nanostructures often exhibit gradients of surface (and/or interface) curvature that emerge from fabrication and growth processes or from thermal fluctuations. Thus, the system-inherent capillary force can initiate morphological transformations during further processing steps or …

Simulation des Wälzschleifens und dessen Einfluss auf die Flankentopografie und Verzahnungsakustik
In der vorliegenden Arbeit wird ein Simulationsmodell entwickelt und validiert, welches die Hartfeinbearbeitung von Zahnrädern durch kontinuierliches Wälzschleifen abbildet. Dabei liegt ein besonderer Schwerpunkt auf der in fehlerbehafteten Prozessen erzeugten Flankentopografie und deren Bewertung …

Modularer Ansatz zur Simulation verfahrensübergreifender fertigungstechnischer Prozessketten
Several modern trends in product development have resulted in the material properties of a part having a greater influence than ever before on the entire life cycle of a product. The ongoing trend towards lightweight structures in the automobile industry, for example, is leading to a steady …

Mathematische Modellierung des MDEA-Absorptionsprozesses
In chemical engineering, absorption processes are used in many cases for the purpose of selective separation of one or more gas components from a multicomponent gas stream. Compared to adsorption, which uses large solid surfaces, absorption has one main advantage: i.e. a countercurrent flow of both …

Prozessentwicklung für die kontinuierliche dynamisch kinetische Racematspaltung
A dynamic kinetic resolution is an interesting and reasonable extension for a simple kinetic resolution. Especially for the connection of an enzymatic catalysed kinetic resolution and a chemical catalysed racemisation very good results are known from literature. Common compatibility problems …

Verbesserte Webmaschineneinstellungen mittels Simulationsrechnungen
The weaving process is substantially influenced by the warp thread tension. In order to obtain good fabric quality at a smooth run of the loom, the optimisation of the warp thread tension is necessary. The tension is influenced by a multitude of parameters, especially the back shedding geometry. …
