This book presents the design optimization method for switched reluctance motors (SRMs) and drive systems. It covers an in-depth literature review on the status and potential trend of design optimization techniques for SRMs, including design theory, modeling methods, topologies, control methods, and techniques for optimization efficiency and effects. Readers will discover new design methods based on the specific nonlinear characteristics of SRMs, and multi-objective optimization methods for the design of high-quality switched reluctance drive systems without or with the consideration of uncertainties, i.e., the deterministic and robust approaches. Multi-mode design optimization method regarding SRMs is investigated and some examples are presented. In addition, some essential trends in design optimization development are presented and highlighted as future perspectives. This book benefits students, researchers, engineers, and companies in the field of electrical drive design and manufacturing. The focuses of this book are different from those of the published books. The advanced optimization methods including deterministic optimization, robust optimization, and system-level optimization are not discussed in these books. Besides, new design method based on the nonlinear characteristic and multi-mode optimization combined with specific application will be introduced to the design of high-performance of switched reluctance machines.

This book presents fused deposition modeling (FDM) which is an additive manufacturing (AM) process to fabricate 3D parts from a build-up of 2D layers. The chapters present an experimental analysis of fatigue characteristics of FDM-processed PLA samples. The results indicate that the concentric build orientation provides highest cycles of fatigue, ultimate strength, and impact energy. The effect of layer orientation on the fatigue behavior of 3D-printed PLA samples is investigated in this case study.

Trotz grosser sprachtypologischer Unterschiede des Deutschen und des Chinesischen sowie der reziproken Verhaltnisse der beiden Grammatiksysteme wird in der vorliegenden Studie der Versuch unternommen, durch die kontrastive Analyse der deutschen und der chinesischen Satzkonstruktionen die syntaktische Spezifik der beiden Sprachen darzustellen und aufgrund dessen Losungen fur manche damit eng verbundene Probleme der Ubersetzung vom Deutschen ins Chinesische zu finden. Besonders zu erwahnen sind die sehr unterschiedlichen Verhaltnisse zwischen Morphologie und Syntax in beiden Sprachen. Daraus ergeben sich spezielle Probleme fur eine deutsch-chinesische kontrastive Syntax. Anhand des Vergleichs mehrerer deutscher literarischer Texte mit ihren chinesischen Ubersetzungen wird hierbei die syntaktisch bedingte Problematik in der Ubersetzungspraxis auseinandergesetzt."
