Herstellung topologisch optimierter Teile

Die topologische Optimierung erm glicht es, Teile zu entwerfen, bei denen das Material im Hinblick auf die aufgenommenen Lasten so effizient wie m glich verteilt ist. Unter gleichen Betriebsbedingungen weisen optimierte Teile 20-70 % weniger Masse auf als herk mmliche Teile, was f r die Flugzeugkonstruktion von entscheidender Bedeutung ist. In den meisten F llen haben diese Teile jedoch sehr komplexe Formen, die mit den g ngigsten Technologien nicht reproduziert werden k nnen. Additive Fertigungsanlagen f r Metallpulver und Verbrauchsmaterialien sind teuer, was ein entscheidender Faktor bei der Entwicklung eines neuen Produkts sein kann.In diesem Buch wird eine Methode zur Herstellung topologisch optimierter Teile er rtert, bei der keine teuren Anlagen f r das Sintern oder Schmelzen von Metallpulvern f r die additive Fertigung eingesetzt werden m ssen - das Feingie en topologisch optimierter Modelle, die zuvor mit einem 3D-Drucker gedruckt wurden.

Manufacturing topologically optimized parts

Manufacturing topologically optimized parts

Topological optimisation makes it possible to design parts in which the material is distributed as efficiently as possible in terms of the loads absorbed. Under the same operating conditions, optimised parts have 20-70% less mass than conventional parts, which is essential in aircraft design. However, in most cases these parts have very complex shapes that cannot be reproduced using the most common technologies. Additive manufacturing facilities for metal powders and consumables are expensive, which can be a deciding factor in the design of a new product.This book discusses a method of producing topologically optimised parts that does not require the use of expensive powder metal sintering or melting additive manufacturing equipment - investment casting of topologically optimised models pre-printed on a 3D printer.

Produzione di parti topologicamente ottimizzate

Produzione di parti topologicamente ottimizzate

L'ottimizzazione topologica consente di progettare parti in cui il materiale distribuito nel modo pi efficiente possibile in termini di carichi assorbiti. A parit di condizioni operative, i pezzi ottimizzati hanno una massa inferiore del 20-70% rispetto a quelli convenzionali, il che essenziale nella progettazione degli aerei. Tuttavia, nella maggior parte dei casi questi pezzi hanno forme molto complesse che non possono essere riprodotte con le tecnologie pi comuni. Gli impianti di produzione additiva per le polveri metalliche e i materiali di consumo sono costosi e questo pu essere un fattore decisivo nella progettazione di un nuovo prodotto.Questo libro illustra un metodo di produzione di parti ottimizzate dal punto di vista topologico che non richiede l'uso di costose apparecchiature di sinterizzazione o fusione di polveri metalliche per la produzione additiva: la microfusione di modelli ottimizzati dal punto di vista topologico prestampati con una stampante 3D.

As a central artist of early modernism, Alexej von Jawlensky (born in Torshok, Russia, in 8 4, died in Wiesbaden in 94 ) considerably expanded the possibilities of painting. Based on an expressive, colorful appropriation of the world, by reducing form and intensifying color, he made his pictures an expression of an immaterial and spiritual truth. Despite the great individuality of his path, his work continues to give important inspirations to painting until today with respect to color, the serial, and the spiritual. The exhibition and catalogue present an exemplary selection of some seventy paintings and drawings and trace the development of the three big topics of " face, landscape, and still life," to which Jawlensky dedicated himself in his work.
