Study of pipe-whip parameters in pipelines
Description
The problem of the high energy pipe-whip, assuming an elastic-plastic behavior for the tube material and taking in account the internal pressure, is studied. The constraints are simulated as bilinear springs and viscous dampers. A general research, based on the finite element method was developed to analyse the phenomenon. The influence of the following parameters: gap, damping coefficient, stiffness, constraints positioning and internal pressure of the tube is studied. (Author)

O problema do chicoteamento em tubulacoes de alta energia (pipe-whip) e estudado, admitindo-se um comportamento elasto-plastico para o material do tubo, e levando-se em conta o efeito da pressao interna. As restricoes sao simuladas como molas bilineares e amortecedores viscosos. Um programa geral, baseado no metodo dos elementos finitos, foi desenvolvido para analise do fenomeno. A influencia dos parametros: 'gap', coeficiente de amortecimento, rigidez, posicionamento da restricao e pressao interna do tubo, e estudada. (Autor)Files
