Desenvolvimento de um protetor lateral em alumínio

In view of the need to develop a device for security and lateral protection, due to the Resolution 323/09 of CONTRAN, which requires the use of such equipment for most trucks and tow trucks, the objective of this work is to develop a project for an aluminum lateral protection device, according to the ABNT NBR 14.148 regulation, that, among many specifications, stipulates that the equipment must support a load of 5 kN and suffer a maximum deflection of 30mm, but does not say what material it should be made of. The reason for choosing aluminum is because of its low density, so as not to significantly increase the curb weight of the truck, which, consequently, reduces CO2 emissions and maintenance expenses. Additionally, this material presents a good resistance/weight ratio, high resistance to corrosion, excellent surface finish and it's fully recyclable; reason why it has been gaining the attention of many industry segments. For the realization of the project, profiles were chosen to make the assembly of the set, and then a finite elements analysis was performed in the HyperWorks software, to verify if the designed device would support the loads stipulated by the regulation. One details to note is that these simulation programs could show inaccuracies, because of the size and shape of the elements that compose the mesh, and for many other reasons, so it is necessary that, even with the results coming back satisfactory, actual physical tests are conducted to validate the proper functioning of the equipment, which was not done for this study

Análise crítica de contratos técnicos como ferramenta para melhoria da gestão da manutenção

Currently, due to the highly competitive search among industries are becoming more tools for managing product that provides higher availability and therefore profitability. Maintenance as a strategic sector and of fundamental importance in business, it seeks to maximize availability and available resources, minimizing costs and waste, which directly impacts the company's results. The present work has as main objective the review of contracts for maintenance services for companies contracted by a chemical company in the Paraíba Valley, since most of its maintenance services are outsourced, and raise these contracts which are more critical and higher risk to the company's success, thus creating a tool for decision-making by maintenance managers in the act of seeking renewals or new contracts to provide services. As a result after drawing up a standard procedure for contracting of services and a better structuring of the same, we developed a method for the calculation of the criticality of the contracts and based on these calculations, charts were prepared which showed that the current scenario of maintenance contracts the company studied. Thus it is possible to evaluate the contracts which are most critical to the success or failure of the company studied, and also pave the way for further studies on how this criticality of a contract can affect the relationship, the contractor x contracted

Desenvolvimento de equipamento LED para aplicação em cultura celular

O estágio realizado em parceria entre o Departamento de Física e Biofísica do IBB-UNESP e o Hemocentro de Botucatu da FMB-UNESP teve como objetivo desenvolver um novo equipamento de luz LED capaz de interagir com culturas celulares. Desta forma foi desenvolvido um equipamento com luz azul e luz vermelha. A luz azul é responsável por inibir o crescimento celular, a luz vermelha é responsável por aumentar o crescimento celular. O equipamento consiste de uma fonte, e dois conjuntos com três LEDs cada. A cultura celular escolhida foi a de Miemola Murino (NS1), uma linhagem que possui alta taxa de crescimento e que foi mantida em estufa e meio de cultura, (simulando condições normais de sobrevivência), sendo irradiada três vezes ao dia. As amostras foram coletadas e contadas em câmara de Neubauer. Os resultados obtidos, quando comparados com o controle, não apresentaram significativa diferença de crescimento quando irradiados com luz LED vermelho. Porém quando comparados o grupo controle com o grupo irradiado com LED azul, notou-se uma significativa redução da quantidade de células a partir do sétimo dia de irradiação. Acredita-se que a ineficácia dos LEDs vermelhos ocorreram pois utilizamos células com metabolismo bastante elevado, dificultando um aumento ainda maior da taxa de crescimento. A redução da população de células azuis ocorre pois a radiação interage com a membrana celular, causando a quebra dessa membrana e conseqüente morte da célula. Outra via para a morte é a lesão causada no DNA das células, que ocorre quando a luz azul é absorvida pela molécula

Analise de defeitos em motores através de vibração mecânica: estudo de caso

Revolving machines are among the most used equipment in general industry and therefore expenditures on this equipment class are a significant portion of the total amount spent by the company. If there is an unscheduled stop of some of this equipment, industrial plants can lose huge amounts of money caused by interrupted production and parts delay. Others may increase significantly maintenance costs due to consequences elsewhere not affected before. Even plant and people safety can be in danger if there is an operation interruption without a backup system start. This work is focused on a rotating system case study which is monitored by vibration analysis that shows that is possible to determine when is the most appropriate time for equipment intervention without any reliability loss just by using a simple and cheap system which is not much used because professionals are not aware to its utility.
