Neste projeto procura-se, numa primeira fase, desenvolver um equipamento e
um ensaio para medir a força de rutura de ampolas de vidro usadas na indústria
farmacêutica, fazendo posteriormente a análise e tratamento estatístico dos dados.
Numa segunda fase, pretende-se conceber um equipamento que, no seu conjunto,
permita executar testes com precisão elevada e consequentemente encontrar
resultados com elevada fiabilidade. Deverá, ao mesmo tempo, ter flexibilidade para a
realização de ensaios em diversos formatos e tamanhos de ampolas, a um custo
competitivo.
O equipamento de carregamento manual que foi construído permitiu, obter os
dados necessários ao estudo do problema. Foi também estabelecido um procedimento
de ensaio para o efeito, que foi cumprido com rigor. Seguiu-se o estudo estatístico dos
dados obtidos no ensaio.
Foi acrescentada a este trabalho, uma análise ao comportamento mecânico do
vidro da ampola, com base em simulação e modelação de elementos finitos.
Com apoio em toda a informação obtida, dimensionou-se um equipamento de
teste de compressão para ampolas de vidro que teve em linha de conta os mais diversos
fatores, fossem eles de natureza técnica ou económica.
Recapitulando, em primeiro lugar, este trabalho foi capaz de produzir, em tempo
útil, informação relevante. Foi rapidamente idealizado um procedimento de ensaio e um
equipamento de carregamento manual, que permitiu a realização dos testes
necessários.
A nova proposta indica um equipamento que tem os componentes suficientes e
necessários para quebrar ampolas de vidro Open-funnel ampoules (Form C), de forma
precisa e fiável. Para além disso, grava a força de rutura e o deslocamento ao longo do
teste de carregamento. Fica assegurado o espaço para futuros desenvolvimentos, com
vista, a testar novas embalagens e outros materiais.
ABSTRACT: This project intended initially, to develop equipment and a test to measure the rupture strength of glass ampoules used in the pharmaceutical industry, then doing the analysis and processing of the data. In a second stage, the aim is to design an apparatus which may run tests with high precision and thereby meet results with high reliability. At the same time it should have the flexibility to conduct tests in various shapes and sizes of vials, at a competitive cost. The manual loading equipment that was built, allowed obtaining the necessary data to study the problem. In addition, a test procedure was set for that purpose, which was met with rigor. It followed the statistical analysis of the data obtained in the trials. An analysis of the mechanical behavior of the glass bulb based on simulation and finite element modeling was added to this work. With support from all the obtained information, a compression test device for glass ampoules was designed taking into account the most various factors, either of technical or economic nature. To recap, in the first place, this study was able to produce timely, relevant information. A test procedure and manual loading equipment were quickly idealized, which allowed the completion of the necessary tests. The new proposal indicates a device that has the sufficient and necessary components to break glass open-funnel ampoules (Form C), accurately and reliably and record the rupture force and the displacement along the loading test. Space is assured for future developments, in order to test new packaging and other materials.
