This diploma thesis deals with the design of the bodywork of a weekend sports car, based on the current Sigma TN vehicle, in order for better appearance and extended usability. The goal is accomplished by a new dynamic exterior design. Where the usability issue is solved by a modular roof system and luggage compartment. This work provides a new perspective on the concept and design of cars designed primarily for leisure driving.

This diploma thesis deals with level of degradation of coating layers of car body by contact with chemicals in agreed time periods. First part is focused on surface pre-treatment and coating process in automotive industry. Description of coating materials is following. The last point of first part is focused on alternative coating technology – powder coating what is raising in customers´ focuses because of higher repeatability of powder cloud. The experiment is focused on coating degradation influenced by seven types of chemicals (petrol, diesel, AdBlue, washer fluid, salt liquid, Coca-Cola, alcoholic liquid) what car users meet every day. Testing samples were two bonnets. One was localized inner and another outside. Degradation of coating layer thickness was a long-time term and we measured connection between time of contact and used chemical. Based on such results we were able to determinate level of damage.

Simulation-based design optimization and finite element method are used in this research to investigate weight reduction of car body structures made of metallic and composite materials under different design criteria. Besides crashworthiness in full frontal, offset frontal, and side impact scenarios, vibration frequencies, static stiffness, and joint rigidity are also considered. Energy absorption at the component level is used to study the effectiveness of carbon fiber reinforced polymer (CFRP) composite material with consideration of different failure criteria. A global-local design strategy is introduced and applied to multi-objective optimization of car body structures with CFRP components. Multiple example problems involving the analysis of full-vehicle crash and body-in-white models are used to examine the effect of material substitution and the choice of design criteria on weight reduction. The results of this study show that car body structures that are optimized for crashworthiness alone may not meet the vibration criterion. Moreover, optimized car body structures with CFRP components can be lighter with superior crashworthiness than the baseline and optimized metallic structures.

O presente trabalho tem por objetivo primário abordar os atuais conhecimentos sobre o transporte ferroviário interurbano e regional de passageiros, com foco na tecnologia dos trens de caixa móvel, também conhecidos como trens pendulares. Como objetivo secundário busca-se analisar a influência dos trens de caixa móvel ou pendulares na implantação e operação de novas ferrovias, com ênfase na adequação em fase de projeto, mostrando-se o potencial dessa tecnologia para o aumento da velocidade média e a redução dos tempos de viagem. São tratados os tópicos relevantes para o transporte ferroviário de passageiros, como o conforto do usuário, as especificações técnicas do material rodante e referências dos custos de implantação e operação envolvidos, mostrando-se também dentro de cada aspecto as diferenças dos trens pendulares em relação aos trens convencionais. Três estudos de caso elaborados terão como objetivo explicitar as interveniências da operação dos trens pendulares com o projeto ferroviário, em especial com o projeto geométrico, e através de simulações de marcha e comparações, mostrar de maneira prática o potencial do uso dos trens pendulares. Através do embasamento teórico e dos estudos de caso, é feita uma análise crítica de modo a possibilitar tanto um entendimento do transporte ferroviário de passageiros, quanto do material rodante de caixa móvel e suas possibilidades. Os resultados dos estudos de caso e a análise crítica mostram uma redução significativa dos tempos de viagem, entre 8,1 e 20,0%, mediante a operação de trens pendulares em substituição ao material rodante convencional. / As a primary objective, the present work aims to summarize the current knowledge on intercity and regional passenger railway transportation, focusing on tilting train technology, also known as car body tilt. As a secondary objective, the present work seeks to analyze the influence of tilting train technology on the design, implementation and operation of new railway corridors, with emphasis on design phase, showing the potential of this technology to increase speeds and reduce travel times. Railway passenger transportation issues, such as passenger comfort, rolling stock technical specifications and implementation and operational costs are addressed. Additionally, different aspects between conventional and tilting trains are also discussed. Three case studies help clarify the correlation between tilting train operation and railway design, especially the geometric design; further, with the help of speed simulations and comparisons, the potential use of tilting train operations are demonstrated. With the theoretical basis and the case studies, a critical analysis is made, allowing as a better understanding of railway passenger transportation with regards to the use of tilting rolling stock and its possibilities. The results of the case studies and the critical analysis present a considerable reduction in travel times, between 8,1 and 20,0%, with the operation of tilting trains in the place of the conventional rolling stock.

A presente pesquisa teve como objetivo levantar dados básicos para posterior composição de indicadores de sustentabilidade, em postos de combustíveis, funilarias e estabelecimentos de lavagem automotiva no município de São Carlos, tendo em vista a busca de soluções para questões sociais, ambientais e econômicas que garantam sustentabilidade nesses tipos de empresas. Foram feitas visitas com entrevistas e aplicação de questionários em cada estabelecimento, coletados resíduos sólidos industriais em quatro estabelecimentos de cada tipo de empresa e em seguida caracterizados esses resíduos. Para a classificação de resíduos foram feitos ensaios de lixiviação e solubilização. Os produtos mais utilizados nas empresas estudadas foram classificados como classe I-perigosos. Apesar disso, os resíduos coletados foram classificados como não perigosos, classe II A - não inertes, possivelmente devido à dissolução dos produtos perigosos. Com base no tratamento dos dados obtidos determinaram-se alguns indicadores que, por vezes, mostraram-se mais eficientes quando analisados em conjunto com outros. Ao se confrontar Indicadores de Consumo com Indicadores de Produção, por exemplo, pôde-se prever a dimensão de lucros e prejuízos sociais, financeiros e, sobretudo ambientais do empreendimento. Constatou-se a partir da análise de indicadores estudados que nas empresas em questão, existe falta de investimentos em pesquisas e tecnologias que garantam desenvolvimento sustentável das mesmas. Existe também carência de investimentos em capacitação de funcionários que busque melhorias na qualidade, no meio ambiente, sociais e na segurança dos trabalhadores, e assegure assim o desempenho sustentável das empresas em foco. / The aim of this research was to raise basic data for composition of Sustainability Indicators in gas stations, car body repair and painting shops and car wash establishments in São Carlos city, in order to find solutions to social, environmental and economical issues. This would ensure sustainability in these businesses. Visits were made with interviews and questionnaires application in each establishment, industrial solid wastes were collected in four establishments of each type of enterprise and then these wastes were characterized. The wastes classification was made by chemical tests. Most products used in studied enterprises were classified as class l-hazardous products. Nevertheless, the collected wastes were classified as non-hazardous waste, class II A- non inert, possibly due to the dissolution of hazardous products. Some indicators have been developed from processing of obtained data. Sometimes indicators proved more efficient when examined together with others. When Consumption Indicators are worked with Output Indicators, for example, the dimension of profits and losses from social, financial and above all environmental area can be provided to the venture. Indicators showed investment in researches and technologies, as well as in training for improvements in quality, environment, social and workers safety would ensure sustainable development in the enterprises.
