Die Additive Fertigung spielt heutzutage auch in der Automobilindustrie eine bedeutende Rolle. Eine Ausprägungsform, das pulverbett-basierte LaserCUSING®-Verfahren, bietet viele neue Möglichkeiten. Im Folgenden wird zunächst ein kurzer Überblick über das Verfahren gegeben und anschließend der Einsatz des LaserCUSING®s im Bereich Automotive anhand eines gemeinsamen Projekts der EDAG Engineering GmbH, des Laser Zentrums Nord, der BLM Group und der Concept Laser GmbH verdeutlicht. Hier wurde auf Basis des EDAG Light Cocoon ein topologisch optimierter und hybrid gefertigter Spaceframe entwickelt. Die Karosserieknoten wurden mittels LaserCUSING® additiv hergestellt.

In this line, this paper presents the development and analysis of a vehicle three-dimensional structure spaceframe type, due to the complexity of the structure were used computational tooling in order to simulate the behavior of statically tubular structure, with the main objective to certify the reliability of the developed project, ensuring safety to drivers. The structure, existing, was modeled in CAD through SOLIDWORKS software, and their simulations were performed using the finite element method via commercial software ANSYS®. The simulationmethodology had the precise definition of loads and displacement constraints to the model in order to make the most plausible model possible. Were then performed computational analysis of rollover and frontal impact in the model (80 km/h e 60 km/h). Through the simulations, it was possible analyze the displacements arising from the critical situations in which the vehicle was submitted are consistent with what is recommended by regulating rules and bibliographies, with this in view that the chassis developed empirically and computationally simulated showed satisfactory results as its reliability and safety, are not required increment bars or modifying the system geometry. / Tido como o principal subsistema de um veículo, os chassis são o elo entre os demais subsistemas e ainda devem suportar diversos carregamentos estáticos e dinâmicos com rigidez, confiabilidade e segurança. Nesta linha, o presente trabalho apresenta o desenvolvimento e análise de uma estrutura veicular tridimensional do tipo spaceframe, na qual, devido a complexidade da estrutura foram utilizados ferramentais computacionais no intuito de simular estaticamente o comportamento da estrutura tubular, com o objetivo principal de certificar a confiabilidade do projeto desenvolvido, garantindo a segurança aos condutores. A estrutura, já existente, foi então modelada em CAD, através do software SOLIDWORKS, e suas simulações foram realizadas através do método de elementos finitos via o software comercial ANSYS®. A metodologia de simulação contou com a definição precisa dos carregamentos e restrições de deslocamento impostas ao modelo, a fim de tornar o modelo o mais verossímil possível. Foram então realizadas análises computacionais de capotamento e impacto frontal no modelo (80 km/h e 60 km/h). Através das simulações realizadas, fora possível analisar, que os deslocamentos oriundos das situações críticas na qual o veículo foi submetido, estão condizentes com o que se recomenda por normas regulamentadoras e bibliografias pertinentes, com isso, tendo em vista que o chassi desenvolvido empiricamente e simulado computacionalmente revelou resultados satisfatórios quanto sua confiabilidade e segurança, não são necessárias incremento de barras ou modificação da geometria do sistema.

Topic of the master’s thesis is design and assessment of steel construction of the industrial building used to glass sand treatment. The building has the top view dimensions 12,0 x 12,0 m and roof ridge height 15,6 m. Disposition if the individual elements was designed according to conditions of the technology and production process. The thesis focus on creating of computational model and assessment to ultimate and serviceability limit states of individual elements. Further thesis contains of design and optimisation of some joints.
